When my engine guy calculated everything it is supposed to make 450hp, you are right, 425hp out of the crate, sorry about that.

I know this is a hijack but the crate motor stuff is interesting. GM claims 425hp with 163 intake and single 4bbl with headers...you have a dual quad setup..haven't seen a cross ram setup like that in a long time....I didn't think the motor really had too much with the big rect port heads and low compression: 8.75 to 1(advertised)..we put the 502/502 cam in and switched to alum heads(shaved slightly)..I still don't think it is all it could be, but it is fine for the street scene.
