ARP Crank Studs for 318LA
I line hone and deck my blocks on all rebuilds, whether performance or stock. Sure it costs more but the factory really throws these motors together and yes, they are very forgiving on how far they can be out and still live but I just like to get everything exact as I can, this is what "blue printing" is. As far as the stock bolts, they are plenty strong for a small block. The main bolts are the same ones as the B/RB. Bottom line is that it is your motor and should built it the way you want and still feel comfortable with it.
