It's totally stock as far as I know. It's a 1969 428 CJ. It's got the CJ heads, with PI aluminum intake, Holley 750. I don't know the cam but I did speak with the original engine builder who didn't recall changing it. So it should be in that 410HP/455lb/ft range that most people seem to think is what a stock 428CJ really had - plus the headers which would add a bit to that figure I believe.
