5.3 or ls 1 heads

[WSSix]

You're dreaming especially with an auto and stock heads. Stall converters make it difficult to measure how much an engine is producing on a chassis dyno. How the car drives and performs at the track is what you'll want to concentrate on. Use the dyno as the tuning aid that it is. Always remember, if you can't put the power to the wheels you're wasting time. So be sure to also pay attention to tire selection, suspension set up, and simply being able to drive it properly so that you can launch hard. You might be surprised how quick a properly setup car with only 300-350 rwhp is at the track or on the street.

I reread your first post. I didn't realize you were going to build it more towards drag racing. I had autox in my mind. With that said, if drag racing is what you're more inclined to do the Torquer 2 cam will be fine. The stock heads will be choking the cam a little but a future head upgrade will work very well for you.

Are you keeping the truck intake or going with a car intake? Truck will work rather well actually. Go straight to an LS6 intake if you have to switch to a car intake for clearance.

3200 stall will work fine with either the torquer cam or a smaller cam. Just make sure you have proper gearing in the rear end too. 3.73 will be loads of fun
