No on the center sides, just the forwards and fronts. It's an engine for sale so phone pics are what I got. I forgot to get the date of the block, but I could get it. I was curious if there were differences between truck and car blocks, in 1955, other than trucks got Mech. lifters and front mounted? Is it possible to put hydraulic lifters in mech. truck blocks before '58 as long as the cam is appropriate?
