Several years ago I went to the county fair on a night they had "monster trucks" and among the field there were 2 Dodge's. Well dodge bodied anyway. One was pretty competitive, the other not so much.
The competitive one had a Mopar big block in it,the uncompetitive one had a Chevy engine in it.
They had a meet and greet on the field after the event you could crawl around and under them and look around, ask questions about all that competed that night.
We found out the real reason the one dodge was such a pooch.
All night the MC was saying that the normal driver was either unavailable or hurt or had an event with his other truck somewhere else that night, something. (It's been a few years)
Anyway there was a substitute driver in the pooch, and just by running the motions they got "points" in whatever sanctioning body they were affiliated with. Obviously not as much as if they had won, but "some".
I found out the real reason that truck was a pooch. It had a Chevy engine in the Dodge chassis.
