408 with a btr stroker nitrous cam and ls3 heads??? I have a 408 stroker I am building. I was planning to go with an aftermarket set of cathedrals once I saved money but a set of ls3 heads pretty much came to me. My cr will be between 11:5 and 12:1 (depending on how much I mill the heads). Anyway, I haven't found anyone else running the btr stroker nitrous cam with ls3 heads. Any ideas how much I will make through a 60e on pump gas and do you think this cam will work well with the ls3 heads? it is a 251/266 .632/.596 112 lsa cam for those of you who are unfamiliar with it. It seems like a good ls3 cam but I have never seen anyone use it with ls3 heads. My goal is 500whp before nitrous. Thanks in advance

500+ with proper tune seems likely enough. Aim higher. Pay close attention to detail, ring fit, valve train geometry, valve timing (installed at recommended number) and go for as much static compression as you can, leave nothing on the table, Mill those heads plenty, Tight quench and use a good intake manifold, I made 535 rwhp with a 383 through an M4 and 8.8 with a pump gas tune. 500 is an old target

What Intake Manifold are you Planning?
The FAST LS3 with Mid Length Runners would be Awesome
With that Cam. Should Peak 7000+RPM & Carry well past
7500. What drivetrain, exhaust, chassis set up more details?
Just re-read 60E, 500-525 maybe up to 550 with
64 Posts advice.
