Twin Plug 72 Car
Hello,
I'm looking into purchasing a car for historic racing. One of the cars is a 72 with a twin plug motor. I am told the motor is valuable. I am not familiar with those motors, can someone please summarize the difference between a stock motor and a "twin plug" (other than two plugs
please? Any idea what twin plug motors are worth?
Thank you.
Roy

You would have to know a lot more about the motor to be able to determine a value. In addition to the specs (displacement, stroke, case, etc.), you'd also want to know the name of the engine builder. Anyone claiming high value for a motor they're selling should include a build sheet with all of this. Otherwise, it's just someone's old project.
There are $20,000 motors out there, and then there are a lot worth less than $2,000. As an example, I have a twin-plugged motor in my 1972 that has no historical or special-interest value at all.

Since twin-plug conversions are much more commonplace than they were several years ago, its difficult to say whether that motor is special or not. One would need a LOT more & detailed information about its internals.
Further, there are several kinds of twin-ignition conversions for 911 engines and some add more value than others.
Metaphorically speaking, "twin-plug motors" usually refer to a high-performance or racing version of the 911 engine and therefore a lot more information is needed to make any distinctions,...
