We are going to install the 241s & see what happens. I was thinking that the car should have done pretty close to 400 RWHP with no tune with Ported 243 LS6 heads.
Does a Tune really pick up 50 RWHP?

So 370 RWHP at 5500 RPM with 243 would be on target for no tune you think?

So had they taken the Vinticator cam up to the intended 6500 RPMS & tuned the car. 420 RWHP was in pretty good reach & we are overreacting at this point I take it.

So.. if I put in a new cam, new intake, and new heads..
I'm going to make less power without tuning for the new combo AND only spinning the motor 1000 rpm's under peak power?
Your shitting me right?

There is a head sticky. The 853's and 241's flow the same. The 243's are better. It really doesnt matter after they are ported anyway. There is nothing wrong with a set of ported 241 or 853 heads done correctly. There are a lot of good ported LS1 castings being used on many cars that make great power.
