I ran the numbers on the block it is a '58 truck engine and it has solid lifters. The engine came out of a 1-1/2 ton orchard truck on on a farm near here.
I totally agree with Arnie258 in that the bottom of the lifter must be convex so that they will rotate.
RF, where do I look to see if the block is cross drilled? I don't have a clue.
