Nitrous limits on a 4" stroke 3.25 main cast factory crank?
With a progressive nitrous controller starting at 20% to 100% from .5 seconds to 2.0 seconds, can a factory cast 428 crank consistently and repeatedly take a 250-300 shot of nitrous?
Block would be a bottom filled .030 over factory 4 bolt with factory caps, ARP studs and long dowel pins. Venolia flat top blower pistons, BBC 6.660 H-beam rods.
