340 Build Advice

Okay I dig the stroker crankshaft suggestions but then it's not really a 340 it's a 416 or whatever, if that's what the OP Wants then that's cool but I thought he was talking about a 340ish =stock stroke cubic inch motor.
I'm definitely not against a stoker. My car is not stock in any way so I don't really care about correctness. I'd just like a fast, fun, and dependable engine. Currently, my car has a tired '78 360 in it with a mild cam in it. It kinda seems to have just been thrown together by someone who didn't know what they were doing (among other things in the car). I have no previous history of its build or what all was done to it and I'd prefer to have an engine built so that I know exactly what's been done and it works for my setup.
