I'm dropping the car off Wednesday to have the heads (2.02/1.60, ported & polished, milled, springs, etc.), cam (224/224 112), SW Longtubes and catback, then off to Atlanta to have it tuned.

It baselined 335HP/333TQ with 1000 miles on it.

It has around 4,800 miles now.

Can I expect upwards of 450RWHP?

I know, everyone hates these threads, I'm just a little excited.

Thanks...

Need details on the car. A4 or M6? LS2 or LS1? GTO or C6?

450 rwhp or more on a heads cam car is alot especially with that cam.

If you excpect that much, you more than likely will be disappointed. like previously asked, a4? m6? other mods? year?

2005 LS2 M6. Only other mod is LPE CAI.

realistically your looking at ~415rwhp depending on how good the heads are.

I talked to the guy again today and he said they routinely do these packages on C5 LS1's and get around 430RWHP. I figured with the extra 18ci I'd pick up a little more TQ at the least. He said he wants to mill the heads down 30 thousandths.

I'm starting to think 430 will be the magic number coming out of this, after the tune of course.

I’m dropping it off on Wednesday, so I guess I’ll post some numbers up in about 3 weeks.

Ok, I ended up getting a 228"/228" .576"/.576" 112LSA and the heads are going to be milled 30 thou. Should we see some good numbers? Long tubes, Full Exhaust w/X-pipe.

what are the flow numbers on the heads?

tanglewood

I won't know that for another ~2 weeks. I'll just shut up for a few weeks. People hate these threads anyhow.
