When I pulled the engine, I noticed the cam was sticking out the back of the block about an inch.... Didn't look at any of the numbers, but it looks like the heads have 1.94 valves and were gone through recently... Have to get the rest of it apart and see if anything is worth saving. Didn't do any measuring, but it's allegedly a 283,,,it does have the old canister style oil filter. Somebody might need some pieces off of it before it goes in the scrap iron pile.....
