If it's from AutoZone, I'd wager it's a 350.

its probably been punched somewhere between .010 and .030 over since it is a reman not only that but i would wager a bet that the mains are atleast .010 undersized (if your lucky) along with the rod journals probably atleast .020 undersized (if your lucky)

if i were you i would take it a part and just make sure everything looks alright retorque the mains and rods make sure everything looks good i dont have much faith in some of the remans from autoparts stores they are made as cheap as possible by skimping on the knowhow of the people refurbishing them

I was told it's at least .030 over. They make everything over bore. It could be 30, 40, 50 or 60. They don't even stock standard pistons. My brother in law used to do insurance work.

I'm sure the crank is probably cut also, but they do know how to use a torque wrench, even thou the guys doing the work are very very low paid.

I wouldn't waste time & money taking it apart. It's fine for driving around at normal RPM.
