[darkfiire5000]

I am buying a 383 complete block for cheap and need o put it on an engine stAnd. So what i need to know is what size of bolts fine or coarse thread so i can mount it to the engine stand

3/8 coarse thread for the 4 top bolts , 7/16 through the bottom 2 holes , I recommend you use the bottom holes but you will need long enoguh bolts & nuts to use them
