Ls2 GTO build I have ported patriots(243's) with oversized valves(iskee springs,valves,retainers) Have been milled guessing compression to be slightly over 11:1 Texas speed v2 cam 112 lsa .595/.598 lift 232/234 duration, typhoon ls2 intake(yes it's cheap but it will work) and a nitrous outlet tb plate kit that has 150 jets in it at the moment..... Bottom end is still as it came from the factory(I put a melling high volume pump in along with new single roller timing kit. Arp head studs and ls9 gaskets. Hoping to make between 500-550 at the wheels on the 150 hit through the 4l65e with a 3600 stall.
Something else I have been wondering is if I'll possibly need to change the gears(3.43s) to run a 28in tire or if the car would have enough power to turn them with the factory gears. With 26x10.5 the car did a 1.8 60ft with a factory converter on motor. I was thinking with a stall,spray and 28's it would be fine and capable of 1.6 60ft. I'm still Irs and with Drag bags so the 28s are just an extra precaution to prevent wheel hop.
