my 1st 340....yea

forged will knock when cold ,on the engines i've seen them in
since i'm building a stock car don't think i need them
so these are the mounts ,one is welded ,not sure if they are the right ones to start with if so will get it fixed right
and my oil pump drive
so not engine related but bought a nice gts hood with trim and inserts
guy has a k-frame and 8 3/4 getting on sunday .....i'll see what else he has

mounts are 318 pieces with the mods to work with 340/360, don't sweat it, they're probably fine enough to roll. or buy some conversion/swap mounts, or they show up pretty frequently here.

don't sweat the oil pump drive. you can buy them new in both the std & HD flavors if need be. yours is the HD version. if the hex is clean where it engages the oil pump and the teeth/shaft don't exhibit excessive wear then i'd clean it up and and roll with it.
