whats wrong with a 2 bolt conversion Johnny K. Did you try L78 Fred??

If you change your mind, I have a 2-bolt June dated standard bore "CE" 512 block and a set of 964 caps, bolts, and sending unit plug.
Also have that shifter nut, if you still need it.

Real 4 bolt blocks are different above the oil filter. You can tell factory blocks from machine shop conversions

2 bolts and 4 bolts are the same casting.

I think he is referring to the machining done above the oil filter. The 4 bolt blocks are machined for an external oil cooler. There are other machine differences as well.

This should explain it.

Easy fix for a good machinist!
