I have the flywheel which was attached to this 318 that will work on an internally balanced engine. The kit I was looking at from scat was the internally prebalanced one already. For main studs I figure if I do want to put better cylinder heads and a bigger cam down the road and make bigger power the bottom end will be solid. I realize my open chambers have no quench but again I was thinking down the road if I go with closed chamber aluminum heads do I need/want to achieve quench if I get compression up to 10:1 with aluminum heads?
I think the new pistons will be about 0.012 in the hole with 318 kB pistons or stroker 390 icon pistons. I will wait to see what the machine says about the bores. If they’re good to go with 0.040 overbore they make stroker pistons for that size. Otherwise I’d have to go to 0.060 over for stroker pistons (icon does not make a 0.050 over piston) not sure if my 1977 318 block can go that big overbore.
if I do the stroker engine my end goal would be to run 11.99 at the track which would need about 420isH hp with a 3000lb duster. I realize it’d need better heads, cam maybe bigger carb, etc... but that is longer term plans.
