I currently am trying to get a recipe for a 427. I am going to take the heads and the crank out of a 396 and match them with a 454 block. I want to bore it .030" over which would make the bore 4.28. I think i'm right on that. My goal is come up with a recipe that would get numbers round 450-480 hp and 500ft/lbs torque. Are there any suggestions? Anything would be appreciated, never built an engine of this magnitude before.
