cheapest build that will make good power and move that charger with authority:

pick up any 360. get some KB107's and have 'em set up at 0 deck. get the heads redone with a good 5 angle VJ. use a lunati voodoo 60403 cam with comp 901 springs, headers. reuse the stock pistons/rods

if you're on a budget reuse the stock 360 intake...if you can afford it, get an eddie RPM or air gap.

carb, for street driving I'd pick up a used eddie 600 or t-quad

second choice, pick up a magnum 360. use the same pistons (KB107). send the roller cam out to be reground to about [Email]224-228@.050[/Email] on the intake, about 4-6 degrees more on the exhaust and about .305" lobe lift. use some gm3100 springs and retainers. use an eddie air gap for mag motors or redrill the mag heads to LA bolt pattern.

a stroker will make about the same HP as a stock stroke 360, just lower in the RPM range, and about 10% more torque, all else being equal (heads, cam, etc). power is in the heads, unless you plan on spending some coin on good flowing heads, I'd just stick with a stock stroke 360.
