Street motor. Dropped off a week ago.
1966 B440 Block, 915 heads, and stock forged steel crank are at machine shop.
Awaiting clean up, magnaflux, and measurements.
Roller Cam is planned. Maybe 9.7:1 compression.
NICE, Since you dropped of the heads... getting them ported? from what I found stock would be the limiting factor. Seen good flow numbers from ported 915 posted on here.
