There is also another set of heads out there that I am anxious to see what they do, they are also on our bottom end again with the same smaller cam. I will keep you all posted about that engine as well.
The final tune and dyno should be tomorrow. If she makes 530, that will put me at about 450 rwhp (6sp).
I can't wait to whip some LS1 butt!

Ugh, not this thread again.
Jim, please let us know what your car makes on the dyno tomorrow. I hope you get all the problems you had today resolved. Let me know if you need any help.

I don't know the rwtq number.
I'm picking the car up tomorrow to drive for a week or two, than send it back in for some more tweaking.

How mild did they tune it for the break in?
AFR in the 330s titanium valves.. etc etc etc.. hm.. im not sure.. something is wrong there. Either they are not revving the car... or the tune is completely way off... got any afr numbers?
410 is a LOT less than what the lsx engines get with a heads and cam packages.

Anyways... with 330CFM heads shouldn't you get to 470+ RWHP with a 383???
The LSx engines are already near the 500rwhp mark and 10.7 in the 1/4
If the heads are up to the task and everything.. there could be 50rwhp...
remember its not only afr that has to be done correctly.. I have gotten 29 rwhp out of pcmforless tunes and 20+ over hypertechs...
with 330cfm heads I would expect more...
Heck I am expecting 410s with race ready AFR 210 out of the box... and nothing fancy...
330cfms in a 383 should mean 500rwhp if you multiply x 1.8 the cfms and then x .85 for drivetrain loss...
Is your an A4? do you have a converter??? that can explain the numbers but will sure perform at the track.
