The group 4 cars were equipped from the factory with engines built by Bud Moore Engineering. But all those engines eventually failed, there is a very good chance that the BME engine could have been replaced with one from Holman & Moody. The motor in Whiplash is a Holman & Moody motor.
Point of trivia, the only Pantera to finish LeMans in 1972 was running a box stock, 280 bhp, hydraulic lifter 351C Cobra Jet, with the following changes:
1. Bud Moore intake with 850 cfm Holley
2. Bud Moore oil pan
3. Cloyes timing chain & steel sprockets
4. Bud Moore ignition system
All of those parts were lifted off the Bud Moore racing engine, bolted onto an engine lifted from a standard Pantera, and installed in the #32 Group 4 race car belonging to team Claude Dubois. The swap was necessary because the race engine had thrown a crankshaft counterweight (mallory metal) from it's Hank the Crank supplied crankshaft, just days before the race, and no other race engines were available . All the other Pantera entries at LeMans '72 dnf'd due to blown engines.
I find it whimsical that the race engines all failed & the production engine lasted the entire race. With multi-groove valves no less!
