The original numbers matching 4 speed trans is already gone, the car isn't the original color, has way different interior in it now, just doesn't matter to me keeping the stock motor. It was an ex drag car, it's been taken too far from stock and cut on, doesn't matter anymore lol.
As far as the short block, I have no idea to be honest. Not sure where the car came from prior to before I bought it. When I bought the car I pulled the engine out and pulled it apart to look at everything, and all looked good so I buttoned it back up and cleaned it up. It never smoked or anything. I put a new intake and carb on it, but that's the only thing I changed. I saw the pistons marked .030 so it's been bored, the rods and crank are stock as far as I can tell, but I'm not a Mopar expert so I don't know for sure. The trans I had built while it was out, maybe a year ago if that. Probably has 200 miles on it since I put it back together. I just want to go a lot faster so I'm building a new engine and trans for it.
