I was gonna go to town to buy one but after talking with my father he told me "theres one in the sheld" so after 2 hours of digging I found it. The engine has been bored .040 over and after eye balling the crank for 5 minutes I figured out the real #-393-2442 and its everyday 350 crank. Soooo after some math work I came up with a engine with 357 cubes rounded up from I forgot now....356.675 something like that. Not the 377 I thought but hey its something lol.
And yet again with some math, if I went and got the 3.75 stroke crank that would make 384.56 cubes...or a 385
But remembering someone saying the pistons has just plain 350 and not an over sized one, I put one on the crank(after getting the crank back into the block...sorry this is like 4am here so I may of just been seeing things, but with the piston in place and under rotation just a hint of light passes through on one side of the pistons. Now on the note of me thinking Im just seeing stuff/not knowing this is normal I found a 4 inch wide plastic top and put it up to the bore, didnt touch the sides. Going back to the piston I a screw driver and poked at the piston and could get it to shift, just a little side to side. Now like I said this is my first engine that Iv taken apart fully, I dont think it should do that? Its not banging off the cly walls but if light can get passed the piston and I can wiggle it around isnt something wrong? Again note even with the piston rings ON light is still showing through and it can still be moved side to side.
