About this creation
Here we see the guys have ripped out the original motor and added a monster big block 454 Chevy motor with blower. For when they absolutely have to get to the fire in a hurry. This modification was inspired by one of Paul Combs fire cartoons where the Rescue unit "Goes from Zero to Insanity in 3 seconds."
