where the cylinder walls extend out into where the cam sits there are chips on the edges of the cylinder walls.. this is a chevy 350 4 bolt main out of a 77 3/4 pickup and im wanting to make a 383 stroker.. i bought it for $50 and im trying to figure out if its better to build it like im wanting to do or scrap it because of these chips in the cylinder walls. i can get pictures to explain better on what im talking about.

thanks Brent

If your talking about the rough edges at the bottom of the cylinder that is normal.

the chips are half an inch wide and about a quarter inch chunk is missing out of each cylinder wall

Bottom of every cylinder? Post up some pics.

Looks a lot like what happens when a rod lets go. It's a little strange there are so many, but it might have been caused by the crank breaking.

If you have another core, trade this block off. Otherwise, as long as the block mags OK, I would just smooth out the edges of the chips and build it.

Check the main saddles real good- if the crank broke, you want to know all's good.

i know for sure the crank wasnt broke i removed it myself. one rod was broken, another was twisted other than that all others were attached.

That is what happens when a rod breaks and pieces gp flying around. Like Cobalt said, IF it passes a magnafluxing, they can be smoothed up and the block re-used.

Hard to tell exactly, but it almost looks like they are where you would clearance for the rod/bolt on a stroker deal - like that was done without grinding... possibly with the rod itself. More than likely, a clean up with a grind would be the easy fix provided no unseen damage.
