as the title states im in the process of a rebuild due to a blown headgasket thus resulting in worn main and rod bearings...before i bring the block to my local machine shop i would like some info on what bearing clearances, piston to wall clearance and piston ring gaps you pros use for a reliable engine...the machinist doing the engine said he rebuilt a number of these motors back in the late 90's, but just to be sure id like these clearances from anyone who has built these engines successfully so i can compare and see if he knows what he talking about. the car will mostly be a street car with occasional trips to the drag strip. only thing im adding to the block is .30 over speed pro forged pistons. any responses are much appreciated. thankyou.
