Running gtslow at the track
Thought I would have a little fun tonight. Brought my stockish 68 400 4 speed 3:55 open rear car to great lakes dragaway. First run was better than I thought. 14.53 at 98.37. Can't launch at all just got to roll out. Next year posi and drag radials might be able to crack into the 13's.

Great looking car and respectable times! If you know the elevation, humidity, air pressure and temperature, you can calculate the corrected time and MPH

Beautiful car! Get that 60' down and you're there in the 13s.

Just about impossible to launch on 355 gear open rear. Just came off idle and eased into it. I have a posi to install. I will update next year. Was fun to run it and get a base line.

Traction is what is holding you back. The mph should easily run mid 13s. I did so with my 67 GTO running in the NMCA Stock ET class back in 95. It ran 13.60s to 13.50s at 98 mph. I had the suspension set up so that the car would almost lift a wheel off the ground. I was sponsored by BFG and ran their drag radials. Some basic suspension mods and tricks allowed the car to hook very hard. I actually broke a ring gear spacer, side gear, and split a non posi case with a mini spool in it. Engine was basically a stock 400 HO. It was all in the gearing, convertor, tuning, and suspension. Car was heavy and weighed 3,960 with me in it race ready. I won the class that year with it!

That’s impressive Mark!
Funny how the article cited your ‘67 as a ‘68. Reminds me of that Seinfeld episode where George exclaims his dad bought a ‘68 GTO and a ‘67 shows up in the scene. I ran my stock ‘69 last summer and ended up in the high-14s. Started a thread on it: https://forums.maxperformanceinc.com...d.php?t=853526 |
