That is cool, and it kind of brings back some old memories. I started my motorsports career in the late seventies and early eighties in tractor pulling. I ran a modifed tractor with a blown 454 chevy in it, until I built a new one with 2 blown 392 hemis in it. I especially loved pulling at all the state fairs in the midwest and southern states. Then eventually everyone started going to the Keith Black, Rodeck, and Arias engines and it just got to expensive.
