Ok so I have:
$1000 for the V8
$300 for beefier brakes
$300 for dual exhaust
$500 for a beefier tranny
$300 for beefier rear end
$300 for misc
suspension bits...
I think the 17" wheels will be fine--or are the base wheels 16"? Heck, I'd take 15" steel cop wheels and swap 'em later.
So that's $2700. These are very rough gestimates of course...
