Ed , my car IS a stick car also........2.98 low , 5.67 Rr. Grs....... McLeod plate , aluminum wheel.
You cant be happy with 1.40s 60s:D

Oh yeah , almost forgot.I have Chassis Works "floaters' on mine too.............with mono leafs. The car was built in early 90s.

I have a 3.19 with a 6.17 at 3025lbs. 2.98 isn't enough IMO

Those are very impressive numbers that you're running Ed. Off topic but if you don't mind me asking, what rear are you running and what kind of gear life?

Dana 60 current ring and pinion has about 70 runs on it.

Those are rear wheel 60 ft times. You wont run as fast as Ed is with a true 1.40 60 ft. Great to see Ed's car running that well.

Check and see if Santhuff makes shocks for your car. They will control the wheelstands. They aren't cheap but are the best. Good to see your car running that strong. That is getting it done!

I'm consistent in the 9.40s and I've NEVER had a 1.20 ANYTHING 1.30s YES..........1.32-1.34ish......
I have a 1.96 low in the glide and a 5.86 in the rear with a 100 inch roll out radial tire. The glide is handicapping me a bit in comparison to the 3 speed cars I suspect I could pick up about .015 with a good 3 speed trans. I have the power but cant run the short times of some of the really fast cars in my class. I have run next to those guys and their short times blew my mind.

I always thought the Santhuff's fronts big difference was their compression valving, controlling the car after it comes down from a large wheel stand. Are their rebound qualities equally unique?

I run nostalgia SS and FX stuff........not current traditional stuff like you're doing but fun none the less......still a lot of work though , mainly because I do everything myself , engines , trans , rear end etc etc........and the body aint what it used to be and is very sore at the end of the day.
A 377 is in the car now but I've been a 9.41@ 141 with the ol' 355......but that engine would vary from that best to a low .60 high .50. 23 degree std runner head.
The 377 is the same engine basically , just the 4.155 bore and more compression. Same heads , cam , intake etc etc.
This is an old video..........I've posted here before , but here it is ..this was with the 355......9.51, 139ish. Launch RPM was realtively low this day IIRC

I expect the 377 to get me in the 9.30s in good conditions.
