Don't want to pop your bubble, I guess 380ish.

He'd do 380 without the cam, my initial guess was 420 and I'm sticking to it.

The reason for my guess. When my car was a six speed (before auto conversion) I had Ghl Bullets, LG Pro Longtubes, 282/232 110LSA and made 386/382. After Vengeance Racing installed Trickflow 220 as cast heads and underdrive pulley I went to 430/418.

Unless he has a factory freak I see NO WAY to hit 420 with what he
has listed. Especially if his is an auto. This is JMHO. I wish him the best of luck reaching his number. Of course we all know how much dyno's can be different.

Well he does have Z06 heads and intake, so basically a Z06 engine. The 228R seems to make around 420 from the searching I've done and is a popular cam, hence my guess.

completely. My build is very similar. Started with a stock '03 LS1 w/LS6 intake. I added:
stock 243 heads
224R/230R .581/.588 113 LSA
AR Headers
Vararam intake
ATI 10% UD Pulley

Made 420rwhp 392rwtq on a Mustang dyno.

Here are my results on 91 winter blend STD 412/402 SAE 396/386

Cold start and first run

Second pull

All and all I'm very happy with my result considering it's a 98 with the 3pin MAF ... Next on mod list is AI or WCC ported 243 with a MAF swap ...

Sweet. 412 Is close enough to 420 for me to consider myself correct.
