Stay from AAM anything

OEM engine block is fairly stout. Proper rebuild should last a while with proper maintenance. For street car, you won't need too much in the way of engine upgrades, but you have a variety of options if you want to beef it up a bit depending on your budget.

Get the EPS oil gallery gasket and hardware kit. Oil pump gears are a known weak point but really only at sustained high RPMs, which shouldn't be a problem on the street.

Are you suggesting sending the block out to a machine shop for reconditioning? I have a call into a local shop but haven't heard back. I would like to keep same compression ratio but upgrade rings and pistons, possibly have the crank worked up.

I know the slippery slope of engine mods well.... it becomes an obsession!
