Freddie a shorter tire also has a smaller footprint! I think that's the last thing you need with a trans brake. Are you running Hoosiers or M/T ? I know with some playing you can get a 28x10.5 M/T under one of those cars........of course if ya already have the 26x10's give them a try......on Dad's 6 cyl nova stocker the 24x9 M&H's are good for about .05 in the 1/8th over 26x 8.5 M/T. good luck & don't forget to play with lots of differant air pressures.........

Greg: I have a set of 26x10 M/T drag radials a little worn but still workable... the 28x10's are also M/T's but these are slicks..

alot of guys I know are running close to the same car, mine is a little lighter, they are using the 28x10's and most are running a 4.10 gear, but also they all run a glide instead of the 3 speed..

yea a glide wouldn't "hit" the tires like that 3 speed. my neighbor/buddy has an 86 Capri (with an 88 mustang frontend) he had a 306 roller motor that ran 10.40's . it has 29.5 x 12.5 slicks & he left the line @ 5200rpms! with a C4! good luck! oh p.s. he has a 347 in the car now (alum head motor) it runs 9.30's!

You need to run the lowest gear you can. I think 430 to 456 would be a good start. From my experience, I think you will see that the guys running the 4.10's have a power adder such as nitrous or a supercharger. What RPM are you expecting it to run?

I would like to shift the car at 6500.. and run through the traps at no higher than 6800-7000 tops.. since I dont have high dollar rods in this motor, I dont think over 7000 is wise.. I dont use stock rods either..

most of the guys running glides around here are all motor.. one of them has a big ole 437 small block in his, so I know I cant use any info he gives..

just trying to get this combination solidly into the 10's so I can run S/ST this year..

I took the car to test it the other weekend.. didnt go so well... my Converter ended up being a junk piece ( broken sprag) no stall at all.. on the brake could only get to 1400 rpm.. then I found out I put the wrong box of springs on these heads.. motor was stumbling at 5500... yet the car still managed to run a 8.45 in the 1/8th.. with a 2.47 60'..

New converter is here from TCI no used junk this time.. and new springs came in today...
