How many rpms do you guys think a 351w can safely handle with forged internals? Still deciding between a 383 or 408 but either way I'll have a eagle forged crank and rods. Pistons will be forged Keith Blacks. Was thinking about arp main cap bolts and a main cap girdle to help solve any cap walk problems. My twin Borg Warner 55mm turbos might not make full boost till 3-3500rpm and that's why I'm wondering how many rpms I can safely spin. Any help would be greatly appreciated.
351w max rpms with forged internals?

forget the KB junk. Go probe, diamond, JE, CP or Ross. Go Scat 4340 crank, Scat 4340 Pro i beam rods, neutral balance to spin high. look at the high hp engines on nmraracing.com. no one runs KB.
u s/b putting this turboed beast in a 69-74 351W block for up to 1000fwhp. any higher than that u need a Boss 351, R351 or dart race block. u could easily spin to 9000rpm in a neutreal balanced race block with a solid roller. HR would be limited to 7K.
