Sounds like a non born with motor, no?
Even the engine bay has day one status. Because this car's unique competition history has this one with the engine out quite soon after purchase, they took the time to source a correct DZ-code 302 cubic-inch motor. Now the special V8 has been rebuilt to look fantastic.
sourced a correct DZ code motor
Seems at bit much, 182k, for a non original motor Z28.
