high rpm and big horsepower = 4 bolt mains, complete forged 4340 steel (crank, rods and pistons) and balanced rotating assembly, assembled with clearances for racing applications. Above is a must for high rpm and high HP engines.

If you don\'t have a crank go with a scat or eagle crank, the cast ones are good for 500+hp or a forged one which is good for a lot more, eagle ibeam rods, arp fasteners for the mains, dart iron eagle heads,or world products sportsman 2\'s, or if you got alot of money AFR makes some decent heads. If you have flat tops and you want 11:1 use 64cc chambers, AFR doesn\'t make that small of chamber though, only 68 or 72 and 76 for all out race.For a cam go with duration @ 0.50 to be around 240 degrees, comp or crane are good. How high do you plan on revving this thing to? Your gonna need a stout combo to rev to 7500 to take advantage of that single plain.Not to mention a big carb.
