Ok. LOL... the guy built indy 500 engines and didn't know a cast from forged crank. I guess I ran the wrong converter, and I put that smooth running 340 in a Demon, right in front of the original 318's converter and tranny, then I put it in a '70 truck, right in front of the original 318's converter and drove it from Illinois to Colo, then it went into a '72 Duster that had a neutral converter, till the car was sold. Purred like a kitten..... :)
Sorry, I had to be a little smart …. LOL.
