out of the dozens of TTY bolts i replaced the heads lift at 25-27psi lol

On stock 4032 and rings I won't run much past 21psi. Also let the car cool down between runs. don't make one pull after another, will melt a piston.

Thanks for the input. The car is a weekend play toy I dont drive it much at all. I bought it in 2012 and have put roughly 3,000 miles on it in 7 years. I will put it down the track once in awhile for the fun of it. I probably wont make but 650 wheel hp for the street and I ld like to get 800 wheel for the track runs just to cut some good times in the 1/8th. Im not much worries about hp numbers long as the car is happy and lots of fun to drive. I have a couple guys in my town that like to talk one is a 306 n/a fox with big gears and one has a 572 crate motor so I just need to bust them so they can shut up.

I have to add I forgot I built the rear end also, I bought the car and dude said the rear was built 2 days later blew the rear end up. I pulled the cover and sure enough it was a stock 8.8. I ended up doing 3:73 ford racing gears, trutrax locker with 31 splines built straight 8.8
