I have the opportunity to purchase a '91 RRC without the engine. I love the classic lines of the RRC, but having owned one previously I like the idea of a little bit more horsepower, a little bit more torque and a little bit more reliability in addition to finding 350's a lot cheaper than 3.9's and 4.2's in Southern California...I'm contemplating dropping in an LT1 using Mark's Adaptors hardware. my only concern right is the wiring. does the existing land Rover wiring interface with the GM motor or would I have to get GM wiring such as from Painless Wiring?
