just for reference, i worked with a guy that put down 420/400ish with a tr230/224. it was a fast90/NW90 and full exhaust car as well, but that should be a given for ta cam.

 

with the mods in my sig (MS3 and 2.5 5.3 heads) with the 3.42's it felt awesome 3 grand and up and with 4.10s the combo is awesome for stock bottom end...i'm just waiting to take it to the track...had rear end and clutch probs...lol, my fault BTW, on the dyno, my MS3 peaked at 6,450 RPM and i have the limiter at 6600, no need to go to 6800 when it starts dropping at 6500, cam is on 112LSA. Its been tuned alot better than it was on the last dyno run...i'm hoping to be around 430RWHP without UD pulley and such
