You might want to try the fox body or SN95 forums. Those guys could probably steer you in the right direction.

That being said.. MM&FF have recently done a couple of 351W build ups. One was a budget build and the other not so much. But they both ended up in the 400-500hp range. Might be something worth researching.

Now here are the parts I am set on so far..

Eagle rotating assembly 408 W
Eagle Specialty Products B14125030 - Eagle Competition Rotating Assemblies - Overview - SummitRacing.com

I originally had my heart set on a Comp-Cams HiEnergy retrofit cam, Victor Jr Intake manifold and AFR185 heads.... But on another site I was informed by 2 seperate people that all I need to do to make my goal is the stroker kit.. To me this doesn't seem right.. People seem to believe these cars where under rated and I don't believe that either.... The intake manifold on this car looks to be restrictive to me and I am almost sure I'll need atleast that along with the stroker kit.... Any help is appreciated, thanks..
