Hadn't been to the Clay City Drag Strip in probably 15 years. I drive past it all the time though. I always viewed Fords as work vehicles, Chevys as play vehicles. You can get more power out of a chevy for the same amount of money than you can a ford. Dollar for dollar, chevy will almost always win. No different than comparing a 12V cummins to any other diesel in the pickup line of trucks. You can get more power out of a 12V cummins than anything else out there, with less money.
My only question is, why go through the trouble of installing a chevy engine and tranny in a ford truck? Why not run a chevy truck with the engine? I guess he just had to do it.
