Stroker 340>416 Build Advice

Thanks for the response so far! To answer some of the questions:
Weight of the car is unknown but Id imagine pretty close to stock as not a whole lot has been done to customize it.
Gearing right now it has a sure grip 3.73 741 case which I want to get a 742/489 case with probably 3.55 to get closer to highway speeds at not a ridiculous rpm and make it stronger for the higher hp engine.
Elevation is between 1kft-3.5kft
As for hp after reading other posts Id be happy with 450-500hp I dont really intend on dragging much or doing cannonball runs haha

A set of mildly ported Edelbrock heads will certainly fit the bill, a nice solid flat tappet cam, and RPM air gap intake will easily meet those requirements. Do yourself a favor and get a custom ground cam whatever you do, well worth the minor price difference. Call Bullet Cams, Mike Jones Cams, Racer Brown Cams. If unsure, err on the smaller side of recommended Cams.

You didn't ask about carbs, for a street car actually driven, I would highly recommend an Edelbrock 800 AVS2, pn# 1913 with electric choke, 1912 with manual. Excellent driveability, mileage, performance, and easy to tune.
