Took the '67 out to Texas Speedway 8th mile today, considering it's my second time to go I think I did pretty well. I fought a vapor-lock problem the whole time, but I finally just resorted to pushing it through the lanes with the electric fan off until I got up to the end. I think I need to reroute my fuel line out of the path of the electric fan - I think it was vapor locking it.

Now it's not a race car especially compared to the ones some of you have, but it beat most of the N/A guys out there, and ran extremely traction limited. I think I could lose .7 seconds based on my MPH.

First run was a [email protected] - my baseline run, forgot to grab the timeslip. Ran a few more without the aircleaner, 9.18 at around 80.0XMPH finally then started picking up timeslips.

Put a 5.5 power valve in, upped the jets two sizes to 72's up front,

9.081 @ 80.78MPH

My 60ft was horrible, and it was all night, due to bad traction on the 35 year old springs/open diff, Radial T/A's stayed around 2.25.

Bumped the timing up to 16º, Dad took it for a spin, cut a .001 light (I call it luck)

9.232 @80.15,

Dropped the timing back down, jetted up one more size, I started to get in the swing, got a decent .004 light,

9.215 @80.85
9.129 @81.23 (.002)

And my second to last run, redlighted at -.64

9.07 @81.20

I'm missing a couple timeslips, I managed 81.87MPH on a .002 light


Overall, it was pretty successful, showed up quite a few of the cars there, and I was one of the only vintage cars out there - most of it was later model stuff. There was a 68 or 69 camaro, but it wasn't particularly fast.


It may not be super fast, but it was a daily driver for a year, and is my first car/engine build ever. It was quite fun.

Sounds like your car is working pretty good.Your right with traction it should easily run 1/2 a second or more quicker than it does now.Whats your combo?

Put some drag raidals on it and you might see 8.50~8.60 at that MPH. Tx motor speedway has a 1/8 mile drag strip now?

81.18 mph was a 8.48 sec run with a 1.84 60 ft. before correcting for altitude at my local track (LACR). It ended up a 13.33 in the 1/4 mile at 100.6 mph. That was with slicks and a gentle launch (stock flywheel and bell). The slicks slowed my car a little over 1 mph in the 1/4 mile. Drag radials should not slow the car since there won't be the increased rolling resistance (I should have just run more psi in the slicks). Pretty darn close to yours! With MT drag radials and a locker/limited slip, I'd think you could easily duplicate or beat my 60 ft and run 8.4-50's all day.


This was my daily driver for a couple years too.

I may have to invest in some drag radials sometime. And maybe a new driveshaft to replace the stocker two-piece thats in there now.

Anyone know what it takes to make a stock '67 two-piece driveshaft give up the ghost?

I found one of your time slips in the Expedition.....9.121 @ 81.81.....R/T .002. You were cutting some good lights.


But the 60' time 2.367

I would guess the u-joints will be the first to go.

On average I lost 2 mph +- with the slicks in the quarter if it makes any difference. Wouldn't want you to throw slicks on and wonder what happened to the mph. Most say it's normal.

I dont' know but I was putting 440 to the ground when I still had mine. I had nitto drag radials on it at the time...
After a couple blasts like that though I started noticing some major vibrations at high speed so I bought a custom made aluminum one and that took care of the bad vibes I was getting. I must have twisted it some because it kept getting worse LOL.

That's good to know... I don't think I'll be making 440 to the ground any time soon.

And the U-Joints are good strong pieces. We replaced them when we did the rebuild, so hopefully I'll be good for a while.

Might try another jet size or two up next time and see what that does.
