im just wondering because im already begining to plan my new engine for my stang and i was wondering about how far you can push a stock block? like hp, rpm's, boost, nitrous and does a main support system work that well?

 

A stock 302 block...I would not exceed 500hp, main girdle or not. A Windsor with a girdle I have seen 750+. The later roller blocks tend to be a bit shy on the castings but still a stronger block compared to the 2blt main 302's. Retro blocks (pre-roller) are thicker in the webbing and a little stronger. But main cap walking is eventually what leads to cracking.

 

now all 351's are just 2 bolt main right? and how many rpms can a w turn?

 

Yes i believe all 351's were 2 bolt. RPM's depend on engine, like cam and heads. I turn mine to 6800 but i have ported trick flows and the cam is 588/622 lift with duration at .050 being 246/259.

 

what kind of time does your car run? what else have you done to the engine? wat kind if tranny ru running?
