stroking a 440??
for any bbm block in my opinion.
where the oil hole from the pump takes a turn into the lifter gallery, the inside radius needs to be ground round so the oil can make the turn. drill the oil feed holes to the mains out to 5/16". where the oil feed for the heads are on each side drill a hole into the lifter gallery and on into the oil feed to the heads. use the correct size bit so that you can tap for a 1/16" pipe plug at the hole into the entrance to the lifter gallery. put a pipe plug in each side. this will give you full oiling to the heads. if you use heads that are built for full time oiling you don't need to do this. chamfer the oil holes on the crank so it speards the oil out over the bearings better. use 360* groove mains. use an external oiling system and a 12qt pan. use the best balancer you can buy. have the rotating assembly balance at a good shop. use a main/block girdle that comes with the main caps and studs. heads studs are best to use also. use the best chain timing set you can buy or a gear drive, the cheap ones seem to work as good as the better ones. you can use hard block also but only fill it up to 2" of the deck or the bottom water housing hole.
