Engine Build For Naturally Aspirated Power
Has anyone had experience with building up the 3V V8 for significant HP gains without a Blower, Turbo, N2O?
What kind of gains could you expect to see with a stroker kit?

You probably won't get the types of gains you would get with a fully build N/A against a Forced Induction car.
Although you could probably squeeze out around 400-425 RWHP with a Big bore (5.2) Stroker kit, Heads, Cams, LT Headers, UDPs, 1 pc lightweight driveshaft, lighter flywheel... and whatever else I'm missing at the moment.

I hear that FAST(a division of Comp Cams) is coming out soon with a redesigned intake manifold that delivers 30-40+hp, so I think the days of a 400+rwhp 3V is just around the corner.A high compression stroker with hogged out heads, radical cams, the aforementioned FAST intake, LT's, an O/R X-pipe and the other knownbolts-ons should definitely surpass 400+rwhp IMO. Different strokes for different folks, I realize not everyone likes FI, although I distinctly remember a tee-shirt at the swap-meet(where that put on iron-ons) when I was a kid(circa early 70's) that said "Injections are nice but I'd rather be Blown" in reference to the different drag race engine set-ups of the 60's

RE: Engine Build For Naturally Aspirated Power
Forged internals are necessary if you really want to blow these new GT motors. I definantely want to strengthen the insides and make as much HP in doing so before I put a S/C on it. It is just safer and more reliable to have a strong motor that can hold up to the rediculous amounts of power some of these 2.6L blowers can fork out.

RE: Engine Build For Naturally Aspirated Power
One of the issues you will be faced with is whether you are building a N/A motor or a FI motor. You should decide because this allows you to choose proper compression via the pistons and gaskets you choose as well as proper cams. If you are building a N/A motor you should consider nitrous as a power adder to get your the power you want. If your building a turbo/SC motor then the sky is pretty much the limit depending on the numbers on your bank statements. Good Luck.
