You sacrifice a lot with a 4" stroke. a 4" stroke is going to need 6" rods, which leaves you a 1.00" compression height- very tight, though it can be ran. The other issue is that you need to clearance the block and many blocks will leak like a sieve after that much grinding.
A 383 or even a 350 can be built into very stout street engines. If you had plenty of cash to through around and an aftermarket block and huge heads etc. then going for max cubes may be a consideration but for your mild built keep it simple and cost effective.
To be honest, a plain old 350 running with some kind of forced induction will give you the most torque/power for the least cost. You may want to consider that option.
