Re: 1971 F100 4x4

I am watching this with great interest Ross..I want to redo the exhaust on the wife's 65..It is very short and has the mufflers under the rear section of the cab and exits in front of the rear wheels.This makes it pretty noisy inside the truck...I am debating on how to do the tailpipes and where they will exit..I would like to leave the spare tire in place so exiting straight out the back will be tricky but still doable I think..May go with a more stock appearing setup exiting behind each back wheel..
How tight are those valve covers to the brake booster?..That is what I wanted to put on her truck as well but I was told they would not fit under the booster..

Re: 1971 F100 4x4

Tons of room to the brake booster, you can run them, its nothing like a Fairlane or Mustang where they dont fit.

As far as the exhaust we used to use Blazer tailpipes on F150s with a gas tank, fit like they were made for it, but only 2.25 inch, so it depends what you need

I run the exhaust including the mufflers tucked up into the frame, then tie two 45's together to come straight back under the bumper. You cant do that with a gas tank as you pointed out, but easy to come out the sides

Been following this one for a while, I'm eager to see how it turns out. Good luck!

Re: 1971 F100 4x4

LOL you've been patient, it was in my trailer for 18 months!

I am hitting it hard now, the Mustang is pretty much dialed in as its going to get until the blower motor next year, so its time to give the old F100 the attention it deserves

Re: 1971 F100 4x4

Here is the final iteration of the exhaust



The camera readjusts itself, you'll hear it, real life is somewhere in the middle. It sure isn't obnoxiously loud, but it isn't quiet either

As much as it pains me as a life-long bodyman/mechanic, entered by birth, next step is to send it to a very good body shop.

Life nowadays is certainly blessed with everything except time. I am the worlds worst garage customer, but I'll have to adapt, or it will never be one color LOL

Re: 1971 F100 4x4

Well, you'd think I was the laziest man on earth, but I did get back to the truck after 2 months

In my defense, as a squadron commander of one of the fastest deploying reconnaissance squadrons in the Air Force, I find plenty of other stuff to spend time on

However, pulled the fenders off the truck, going to replace one, freshly edge and undercoat both and replace all the bolts and clips with repop clips and plated bolts to make it look pretty

Once that is done, shooting for fresh base/clear in the original Candy Apple red



After THAT I need to decide if it gets forced induction on the 390 or does it get the 489 from the Mustang and build a bigger FE for the car, but if I think about that now I will NEVER get it painted LOL

Re: 1971 F100 4x4

Started fitting the new LF fender, tomorrow is the RF and hood, once I get the lines where I want them, I'll pull them back off and edge it as well as paint the upper and lower valance.

Re: 1971 F100 4x4

Well with an unheated garage it's a bear to get motivated to do much.

Matter of fact, might take another hiatus to heat the darn place

Re: 1971 F100 4x4

Well, I am not sure if this thread can be considered "Making Progress" because I dont seem to be putting things together, only taking them apart LOL

The truck is at the bodyshop, motor is out, and cab fenders, doors, etc are all sandblasted and being painted.

I decided to reseal the motor which turned into a rebuild, which turned into a stroker LOL

I was mistaken which cam I put into the truck in the late 80s, early 90s, but after disassembly, here is what I had. Keep in mind it was 20 years ago!

OLD
- 390 + .030
- 8:1 compression, .130 below deck!!!!!!! Darn cheap builder pistons
- Unported heads D2TE-AA heads, 2.03/1.57 stock valves, 2 piece retainers and springs at 70lbs closed/200 open
- 270H cam
- Unported Edelbrock Street Dominator
- 750 Holley
- Hedman Headers
- Recurved Duraspark

The new build will be a combination of old and new and should make a heck of a difference

NEW
- Same block, .040 overbore, torque plate honed, square decked .015 cut
- 418 cid with internally balanced SCAT 3.98 crank, for 9.97:1 compression, .010 deck clearance
- Well ported D2TE-AA heads, med riser intake dimensions, 2.09/1.66 undercut stem valves, light retainers, 110 closed, 280 open, Viton positive located valve seals
- Heavily worked Edelbrock RPM intake (off my 489 from its pre-EFI days)
-750 Holley (although I may try my 1000 HP series vac sec)
- Same 270H cam (with the head and intake work, should keep the range where I want it, but admittedly its a bit small) Should peak at 5200 perfect for the 4x4
- Hedman Headers
- Duraspark

The truck should be pretty strong, simulators all say 425-440 hp, I expect closer to 400, but regardless, with the added compression, cubes and airflow it should be MUCH stronger

Re: 1971 F100 4x4

I've been watching this one for a while, can't wait to see and hear it up and running! Ought to be plenty of power to get you into just enough trouble.

Re: 1971 F100 4x4

With all good projects, I couldn't leave well enough alone. Going BIGGER!
Here is a recap

OLD

- 390 + .030
- 8:1 compression, .130 below deck!!!!!!! Darn cheap builder pistons
- Unported heads D2TE-AA heads, 2.03/1.57 stock valves, 2 piece retainers and springs at 70lbs closed/200 open
- 270H cam
- Unported Edelbrock Street Dominator
- 750 Holley
- Hedman Headers
- Recurved Duraspark

EA3.0 says 353 hp at 4500 / 423 ft lb at 4000
(Optimistic, but good to compare each option)

VERSION 1 (cast away for lack of cubes LOL)

- Same block, .030 overbore, torque plate honed, square decked .015 cut
- 418 cid with internally balanced SCAT 3.98 crank, for 9.97:1 compression, .010 deck clearance
- Well ported D2TE-AA heads, med riser intake dimensions, 2.09/1.66 undercut stem valves, light retainers, 110 closed, 280 open, Viton positive located valve seals
- Heavily worked Edelbrock RPM intake (off my 489 from its pre-EFI days)
-750 Holley (although I may try my 1000 HP series vac sec)
- Same 270H cam (with the head and intake work, should keep the range where I want it, but admittedly its a bit small) Should peak at 5200 perfect for the 4x4
- Hedman Headers
- Duraspark


EA3.0 says 436 hp at 5100 / 488 ft lb at 4000
(+83 hp / +65 ft lb over original 397)

NEW PLAN (All parts are prepped and I will bring for balancing, just waiting on new harmonic balancer)

- Same block, .030 overbore, torque plate honed, square decked .015 cut
- 445 cid with internally balanced SCAT 4.25 crank, for 9.97:1 compression, .010 deck clearance
- Probe forged pistons (nice and light)
- Reciprocating weight down 4.4 lbs and rotating weight down 4 lbs over stock 390!!!
- Well ported D2TE-AA heads, med riser intake dimensions, 2.09/1.66 undercut stem valves, light retainers, 110 closed, 280 open, Viton positive located valve seals, Precision oil pumps rocker end stands
- Heavily worked Edelbrock RPM intake (off my 489 from its pre-EFI days)
-750 Holley (1000 HP series vac sec more likely now)
- Same 270H cam (admittedly its a bit small, but I will crank it back to 110 ICL to let it hang in a bit longer) Should peak at 5000-5200 depending on how well the heads flow, perfect for the 4x4
- Hedman Headers
- Duraspark

EA3.0 says 470 hp at 5000 / 530 ft lb at 4000
(+117 hp / +107 ft lb over original 397)

Of course the numbers look great, and ARE optimistic for every one of the builds, but the difference from one to another should be closer.

Sold all the 416 goodies pretty quick, hoping to get this one on a dyno and see how it does compared to the guessers

Re: 1971 F100 4x4

The new motor plans sound awesome...I would love to put something similar into the wife's 65.
