Just need to the size and length of the bolt that holds the oil pump on a small block. I know I have one but want to be sure I use the correct one.
Thanks

ARP's catalog list the stud as 3.125" length for high volume. Standard volume I assume is shorter, but no detail.
(pg 50)
As a bolt, that probably equates to about a 2-5/8" - 2-3/4" UHL.
7/16 - 14 ;)

That's a special bolt - P/N 3892678 (7/16"-14 x 2") for small-blocks, 3860382 (7/16"-14 x 2-23/64") for big-blocks; don't use a substitute unless it's made specifically for that application.

Thanks for the info once again JohnZ
