I know this isn't a chevy forum but id figure that yall would know more about it than me but my 1999 chevy 350 vortec motor blew up but the good thing is that just the main bearing on the crank and the crankrod bearing is bad and the crankshaft is bad the top end is fine no scuffing of cylinders or pistons .... what I was wanting to know is what is the stock bearing sizes for the crank rod bearing and main bearing for crankshaft and if possible the
Pistons and Rings sizes

 

Your First problem was It's a Chevy
