ya i mean the rods and crank are either gonna be eagle or scat. Since those are the forged pieces that are within a "reasonable" price. However ive heard a lot more horror storys about eagle than i have scat which i why im gonna get a scat crank. Rods...who knows might just be eagle but most likely scat as well.

Anybody have a "what they think" is a better cam. Everything else im already dead set on but the cam im not 100 percent sure of yet. Must be solid roller tho. Lemme know guys. Streetability doesnt really matter. Should be within the 3500-7500 rpm range duration wise. Also under .660 lift and over 600 lift with either 1.5 or 1.6 ratio rockers. Lemme know fellas. Also lobe seperation at 106/108 range.

the first and third cams made about the same peak power but the curve was flatter with the first, about the same power as the first dyno I did for you. increasing the exhaust to .655 flattens it out for about 1000 rpm at 550 hp with the .640 it's about 500 rpm
