Hey guys, I just registered myself and thought I might get your two cents about my build that's going to happen. I'm going to be building a stroker w/ the V07 crank, F54 block with a 1mm overbore from stock, a road race cam from rebello and flat top pistons. I'm going for 10:1 compression. My real question is fuel delivery...some one somewhere said I might have to go to 45's to compensate for the new displacement. I nave 40dcoe webers now. I also have a fuel injection N42 intake. Should I switch to MegaSquirt and go the F.I. path or stick with my webers. Will I need to upgrade to 45s? :gotme

45's are delicious. Injection is more efficient though. As much as I LOVE triples, I think I'd be inclined to go fuel injection.

I'm on the fence with it. I think I'll just stick with the 40s and see how it reacts. I don't want to make this build extremely exspensive all at once. Injection may come later.

I'm a megasquirter, but I do love the triples. 40's are small for the 2.8 much less the 2.96 you are building.
