hi there i am do a winter build on my engine. i already no my direction just wondering the power out come. i am hoping that around 420RWHP would be possible.

383 hydraulic roller(565/575lift)
11:5:1 compression
AFR 180cc heads(flow 260 intake/207 exhaust)
30 pound injectors, 58mm tb
edlebrock LT4 raised intake(possible stock ported?)(any power difference)
headers. 3" exhaust
4l60e auto, aluminum drive shaft

The old AFRs suck and the new ones are at best untested so you would be the ginea pig. Even AFR fans will tell you the old small port stuff is bad.

The Edelbrock intake sucks, better off with a ported stocker.

Honestly for a modest goal like that you can get there with ported GM castings for the heads and intake.

375rwhp, 400rwtq. Not enough headflow for that big of a motor.
