Re: 87 5.0 tbird Flat top pistons? Reply #15 – April 15, 2019, 01:06:37 PM Thanks for the info, im not going that drastic with it, but gives me some ideas of how it would perform. This is just strictly street. Probably go 2000 to 2200rpm stall to get the engine in the torque range of the cam. Supposedly the cam operates between 1500rpm and 5500rpm. The 4r70w gearing will help, 2.84 1st gear with 3.27 final is like having the original 2.4 aod with a 3.73 on launch Quote Selected Last Edit: April 15, 2019, 01:22:49 PM by Scottyflm
