We machine quite a few blocks for 383 engines we sonic test the block, bake and blast, line hone with an ARP bolt kit, square and deck, stroker clearance, bore and plate hone and that runs 595.00
On the 383's we when there is some spare time in the shop we put on 4 bolt replacement caps or if its a 2 bolt we machine for splayed center caps.
So far all the rotators we have used we used only forged cranks and 6 inch rods only. the cranks we have been using are the Callies cranks as we can buy them cheaper the Scat and they seem to right on for sizing.
