Oil pumps on 235 Chevy 6s
I took my '56 235 apart getting ready for a complete rebuild. I worked really hard to unbolt the oil pump from the block. Chevy used headless bolts so I had to be real creative but got it unbolted. Then I found out that these bolts are that way to prevent removal; this part of the pump is line-bored at the factory. I was told that since I removed it, the block is ruined. Is that true? I am going to try to bolt it back anyway 'cause I can't immagine the tube that was taken off can't be put back close enough to work fine. I can see how mixing tubes from different blocks could cause problems.
