I tore down a 283 on Saturday that I picked up to rebuild to put in my 63 chevy truck.This engine was complete from pan to aircleaner . the guy I got it from had it in a 66 that he bought and he said it would not run and one cylinder only had 30 psi on it so he pulled it stuck it in the back of his garage and bought a big block for his truck.What I found in the engine was a hole in 2 of the pistons and all the pistons had been intalled backwards in the block with the notches facing the back of the engine.Its looks to me like some one at some point tried to put new ring on the orginal pistons .None of the rods had been stamped in order from front to back and the block is standerd bore.There seems to be no damage to the cylinder walls that I can see and the crank and piston rods look fine.This block has casting numbers of 3756519 and date of J250.I plan on taking it down to the machine shop and have them clean it and magnaflux it.Do you think this has caused ant major damage to the block?
Thanks for any help you can throw my way.
Jim
