Has anyone got specs on a ideal 360 build?
like patrick said, how are you gonna use it?!
but, assuming a street cruiser, weekend toy in a car...
my ideal build would look like this:
KB Hypereutectic pistons, domed w/valve reliefs std bore or .020/.030 if your block needs it. $250
Eagle forged rods $230
Stock cast crank -- free
Balance job, crank polish, etc. ~$200
Rings $60
that gives you a bottom end good for about 10.5:1 compression and good for probably 500 hp for less than a grand. or if you need block work, then maybe you'll end up at $1500-2000
some $1500 edelbrock heads
intake/headers/carb/cam of your choice, and you've got a 450-ish Hp small block for less than the price of the "380hp small block crate motor"
if you plan on a piston swap, I'd go KB107's, they're flat tops, set them for 0 deck, .039" fel pro head gasket, and 63ccish heads yield about 10.6:1.
I'd reuse the stock rods with new bolts, reuse the stock crank.
if your heads are usable, use hughes #1110 springs and their retainers. have a valve job done, opening the seats up to 1.9/1.605" (the stock VJ is undersized), open the pushrod pinch up some, and do some bowl blending. if your heads are unusable, I'd get some enginequest 318B's or some RHS's from either hughes or Brian at IMM.
intake, I'd use an edelbrock air gap
I'd use 1 5/8" headers
cam, I'd look for a roller in the 220-224@.050 duration, with about .340" lobe lift max. I'd probably use stock rockers for now.
I'd probably see if the stock cam can be reground by bullit cams using their HR274/340 lobe for both intake and exhaust.

I'd wager it would be an honest 370-410hp depending on carb and how well the heads are prepped.
