I believe the engine is a Chrysler Hemi-derived unit.
As far as the wheel layout,the rulebook says 4-wheels.
She is very fast.
Goldenrod was designed for 555-mph.She ran 421 mph,one-way, in 3rd-gear on 'slush'.She averaged 409 and change.Chrysler had more powerful engines waiting in the wings.She'll never be raced again so we'll never know about that cars potential.
I would anticipate a new world record for Speed Demon next years season.
Nice tail!
P.S. a de-winged F-14,or F-18 will run soon at Edward's Air Force Base,California,on Roger's Dry Lake.
