Buba, I have a couple albums that contain some photos taken at Buck Motorsports Park. Links are below, here are a few pics to whet your appetite:
Cummins KT in a cabover Brockway.
Hard to get good night-time action with my camera. I believe this is Tom Lindsay's KW also with Cummins KT power.
This Marmon had a Cummins V903 for power.
I'm certainly no expert, but i have picked up a few things. Engines of choice for the pro pullers are Cummins KTs (only available in resin), Detroit V12s (Bandag Bandit), Cat 3408s and Mack V8s. You will occasionally find a Cummins NTC or V903 (First release ERTL International Transtar conventional) or a Cat 3406. The pros run two or more turbos, water injection and ungodly fuel pressures.
