Re: 65' Mustang GT

While heating and bending the headers upwards when they were in the car, I had one of the tubes collapse:



That's not a problem to take care of any more. I searched through my box of exhaust pipe and came up with a suitable bend:



Marked where I wanted to cut and went after it:















I also added some piping:







Decided I would like to coat my own headers, inside and out using this Eastwood product which is supposed to cut down on heat and is good to 1800*s:



First I had my headers sandblasted so the paint would have something to grip onto:





The coating comes with a 2' extension tube. I wore gloves as its a very messy process when doing the inside of the headers:



I first practiced on a small section of discarded pipe to see how well the material covered:



It actually sprays out way, way to much material at a time. I ended up swishing around the puddle that accumulated inside the headers to ensure all areas were covered. Luckily it dried in only a few minutes.









Since the exhaust pipes were aluminized, I touched the welds up with another Eastwood product:

Re: 65' Mustang GT

Although the 90/10 Calvert shocks worked fine on the car, I decided it was time to go with double adjustable front shocks. The car needs to hook with the small 28x10.5 slicks and yet not drag the rear bumper going down the track. These Viking branded DA shocks are expected to be a great help in controlling what the front end does.

These are the race bred Crusaders:



The Viking is made of aluminum and looks like a work of art when compared to the CalvertL



One knob is for compression and the other is for extension:



Each knob has 18 different settings to give more than 320 possible combinations. The knobs are accessible through the coil springs and won't need to be removed to do adjustments. I suspect the tire will need to come off though . . . . . On the rear I am going to give the Rancho 9 ways a try but suspect I'll be replacing them too with DA's to improve traction.

I built an adjustable stop for the lower control arms and welded them into place the frame. The stops allow me to use the shocks through their fullest range without over extending the shocks or I can narrow the range of movement as another method of preventing nose bleed wheel stands:













I discovered that the above bracket had some flex to it and so I added another support that triangulates the outer reaches of the bracket to the frame. (not shown.)

Hopefully the above 2 solutions will keep me from needing wheelie bars.

With the motor, full drivetrain and exhaust installed I dropped the car to the ground to check out the front end ride height after doing both the Arning/Shelby drop and cutting 1 1/2 coils from the new Moroso 242lb springs. I may have went too far . . . .

The front end is definitely lower now than it was last year:






Unfortunately the car hasn't been on the ground long enough for the springs to settle and so I am concerned about only having 4 1/4" of ground clearance for the headers. I feel that there is a good chance that I'll be buying another set of Moroso's and being a little more conservative with the coil cutting. Even so, I'm going to give it try for now (with stiffer shock extension.) Really hoping the headers clear the trailer floor while loading/unloading.

Re: 65' Mustang GT

ITS ALIVE!!!

Engine fired up on the 2nd rotation, great oil pressure, no misses, no leaks, no smoke, no blowby and the tail pipes are still clean inside.

Only problem found with the car is that the new fuel gauge sensor is way off in accuracy--10 gallons now equals a little less than 1/4 a tank . . . . .

The motor probably ran 45 minutes total in 3 separate sessions, but only in the garage. Time got away from me and I didn't get the chance to properly adjust the clutch, align the front end, install the shocks, tower braces, and hood to go for a ride. Still it was a quite satisfying day knowing my baby is awake and well.


Even with the big tube exhaust and straight threw mufflers, its pretty docile sounding with the 2 1/2" tailpipes installed as you can tell by the video. The SR valvetrain is actually louder at idle . . . .










I can't really rev it as I live in a residential area 1 close neighbor who doesn't appreciate the fine sounds that my garage produces (old bitty who drives a Chebby product.) She still gets a good taste of it when I load and unload the trailer on race days . . . . .

Once the motor warmed up I readjusted the valves to specs, doing one bank and then warming it up again before doing the other. I did move the car in the garage a few feet for and aft under its own power. Its going to rain all day so I won't get to do a shake down cruise today either but it will be ready by the end of the day.

(Sorry for the underlining--can't seem to shake it after linking the video)

Thanks man!

It rained on Sunday so we were garage bound. Tied up most all the loose ends such as install the hood and aligning the front suspension. Every thing is going smooth so far, except the new fuel sending unit is way off. Started the car and let it warm up and adjusted the carb idle. With the big cam it really doesn't want to idle under 1200 rpm's (which is close to my 1100 target.) I may be running too cool of a plug but until I get to drive it I won't be able to sort it out.

Hopefully put a few miles on it next weekend.

Re: 65' Mustang GT

That thing is going to be an animal Dennis!

What kind of carb are you running? I'm thinking my 750 Holley won't quite be enough for the 408 I'm building.

Re: 65' Mustang GT

Dennis, as always beautiful work!
Sounds awesome, even double up on the mufflers....


I really like the suspension stops. Wonder if they would also work as a stop for lifting the car on jacks, to keep the suspension from drooping? Ive seen brackets or tools you can insert between the fram and LCA for this, but just a matter of turning a bolt in is nice, just have to mark the bolt to return to your tune spec.


Also love the Vickings, you say significantly less than other shocks, .e.g AFCO? I may need to back schocks as my relocated shock mounts and spring mounts, I retained the old Ranchos, and may need to switch to a eye end on top using a modified mount.


She sounds great though, beautiful work on the engine...love the splash shield.

The Duane Busch specified carb for my combo has 1.47-1.50" diameter throttle plates and as far as I know can only be supplied by a custom carb place. The next closest option that I found is a QFT 950 as it has 1.45" plates.

Before I decide what I am going to buy another carb, I'm going to try the 950HP (830cfm and IIRC, 1.37" plates) that I've been using for a few years. If it allows me to tap the 9's once in a while (or darn close to it) I'll continue using it. It hasn't let me done yet . . . .

Actually a 750 would be decent on a street car. Your probably only giving up 10-15 HP over the 950HP that I use.

Re: 65' Mustang GT

Good to know! I plan to get it running on the 750 for the time being and if I come across a deal on something a bit bigger, I'll jump on it.


Also, changing gears a bit, but looking back at your suspension droop limit brackets reminded me of a buddy's drag car a few years back. It was the other brand but nonetheless, he controlled droop with a bracket that tied to the bottom of the upper shock mount and had a flexible nylon or steel cable (can't remember) that tied into the UCA to limit travel.
I thought it was pretty slick and figured I'd throw my $.02 at it.

The Holley 750 or 950 would be your best bet for street. You really do not need a 850 or 1000 as they have larger venturi's that would more than likely create a dead spot when driving when not a WOT. Note that most other carb manufacturers rate their cfm flow differently than the way Holley does. In that respect, it can be a confusing mess without doing your research.

I considered the cable limiter but was unsure if it would work the way I wanted it too.

Re: 65' Mustang GT

Finally got some nice weather and got to go for a ride. My typical engine break-in includes a hard run up a PA mountain, followed by lugging the motor down the other side in a lower gear coast. At the bottom, I turn around and do it all again.

At the top of the mountain there is a small pull off so I decided it would be a good place to video the car running. Not going to disturb anyone there . . . . . .



Lest you think our mountains are puny:

Tailpipe video:

https://youtu.be/0CfylWjG7Og

Car is running great and I am confident enough to take it to the track next weekend (weather permitting.) Also the steering mods and new front shocks are working great as the car didn't handle worth a crap with the old 90/10 drag shocks.

The motor pulls hard and I took it to 7K in 4th gear going up the hill. From a dead stop it didn't take long to see the shift light come on in each gear . . . . Since the old motor also pulled hard too, my seat of the pants dynometer really couldn't tell the difference from old to new. I do know that this motor comes into its own after hitting 5K rpm's. I expect to be shifting at 7300-7400 at the track.

After the 55 mile ride (including a trip through the car wash) I took the car home and changed the oil. This gave me a chance to try out my new Longacre oil filter cutter:







I chose this one because the reviews were very good and it has a replaceable blade (which the cheaper ones don't.)

I put the Purolator filter in the vise and after 4-5 rotations it cut the top of it off smoothly with little effort:





It was easy to pull the filter element out:



Just a few traces of odds and ends crap was found in the filter and nothing but an oil/assembly lube mix in the oil. All is stuff that you shouldn't worry about at the first oil change after a major rebuild. She ought to be good from here on out.

Tomorrow I plan to warm it again with another ride before rechecking the valve adjustments.

Re: 65' Mustang GT

The first track outing of 2016 is over and the T&T gave me a lot of new PB's. Best ET was 10.21, best 1/4 MPH was 132.95, and the best 60'er was 1.445, all being PB.s. I was expecting a little more out of the first 2, but the 3rd one blew me away and these were last years slicks that didn't seem to hook worth a crap then.

Off the trailer I got this timeslip (318H):



It felt good in the upper rpm's but needless to say, I was extremely disappointed with the results. Comparable with the old motor in the hot August heat. A quick check of the plug wires revealed why--apparently #8 wasn't fully attached on the plug and had fell off.

The second run was much more fulfilling and representative of what the other good runs of the day were:



On the 3rd round I upped the timing to 33* from 31* and lost a tenth:



4th round I put the timing back to 31* and took a solo run:



5th round I flubbed a shift:



Too bad as the 60'er was great for the car.

6th round was uneventful:



7th round gave the best ET:



8th and final round gave the best MPH:



Some of the incrementals don't make sense (IE 126.56 in the 1/8th??) but overall there is a recognizable pattern.

Obviously I need to work on running a Sportsman's tree (I'm Protree trained), but that's OK because I was enjoying the ride from start to finish. The trip down the track seemed like a blurr as the car accelerated much harder than before. As I got comfortable with it I shifted at 7500 rpm's. I didn't play around much with the 60'er as I forgot to take the laptop to download the clutch data to see how the power was being transmitted to the ground. I also forgot to grind down the spark plug socket that I use at the track so that it fit the new heads/headers. I did manage to pull 1 plug after a few runs and it was white, showed brown at the base, and had no detonation spots on it from running straight 93 octane Sunoco pump gas.

My impressions of the car is that the 2nd gear burnouts were crisp and didn't lug the motor down like before. The front of the car came up during each launch, but not as high as I thought it would nor as high as it has been in the past. It didn't matter as most of the runs I had decent traction off the line and that should improve further with a little work. Gear shifts came quick and the finish line went by fast. The suspension work I did over the winter paid off as the car did not act the least bit hairy on the top end, like it did most of last year. It was a smooth straight ride down the middle of the lane. Braking in the shutdown was also smooth as I had upgraded the rear brakes to 11 2 1/4" drums from the factory 10 x 1 3/4". I'll detail the swap in a later post.

There are some improvements to be made, such as getting a handle on the clutch and possibly buying the carb that Duane suggested for my build. I reused the old 950HP which is about 830cfm to see how it would do. I'd say it didn't do too badly using last year's tune but I know it is pretty much maxed out. I would also like to see how she would do with a fresh pair of slicks, which should happen before our big Prostick Memeorial Day weekend. My overall goal is to tap the 9's occasionally, but not enough to warrant needing a full cage.

After the final run I pulled over on the return road and took this short video of the sound of the exhaust (1 7/8" tube headers, 3.5" collectors, 3.5" pipes, and 3.5" race bullets):


This is the exhaust used in the above video:



Can't wait to check the car out before the next outing which hopefully be Friday (looks like rain) or Saturday this coming weekend. If I must wait until Saturday, I'll more than likely head to the other local track which is typically .1 faster for me.
