00427 street roller and a 66200 lifter set will be a sweet package. the cam is a custom once you add a FO swap. cost is 319 no swap 440 with swap. lifters run you $430 when you buy with cam. limited warranty is included with purchase of both.

this is a good solid roller for hi use on street. will rev to 7k and not go stupid like a hyd. does up there. no hyd. at all for me on a build like that , youll have to be above 6k rpm to make it get it on so no hydro lifts.
