After removing the 4.3 V6 that was originally installed, Kevin procured a 6.0L Cadillac V8 from a late model Escalade and shoehorned it into the Bullfrog. The V8 actually fits well, but the big aluminum Ron Francis radiator required massaging of the headlight buckets as it was so wide. The radiator came with a shroud and twin electric fans. The workmanship is superb and the Bullfrog never gets hot, no matter how hot the day is or how slow the Bullfrog is crawling. The finned power steering cooler is mounted in front of the battery. Attention to detail is evident here, where even the valve covers are painted to match the Bullfrog's green paint. An Optima sealed red top battery is mounted where the brake master cylinder usually is.
