i just took the suppose 350 apart to find out what everything look like b/c i am rebuilding to put in my blazer. the guy i bought it from said it didn't have many miles on it. when took the heads off. i found out that the motor had been bored 60 over. do you think i should go ahead with that block or go with another block that i have. everything looks good so i could just hone it out and put a rering kit and new bearings it and go from there.
