summit racing,(Sealed power W244NP80 is i recall)that where i got mine... have to go to total seal for the rings
OP. the above was for a turbo base but enough motor to get you by... a true na build will have more like 10:1 compression. bump the cam up to the 230 @ .050 and about .500 valve lift .370-.390 lobe lift on stock rockers. 106-108 LSA installed 4 degree's advanced. nice lobe and runner up to 5800 or so on pump premium.
gonna want a 600 vac secondary holley carb, dual 2.25 into single three inch.
