Im trying to get a 241, but the one I might be getting would be electric and my tbi system (out of a 1989) is mecanical from the factory. What would it take to have an electric speedometer? Also, should I just buy the stuff to go mechanical instead? The reason I ask is when I go from 208 to 241, I want to put a SYE but from what ive read, the super short will work with the pass drop if its electric instead of mechanical. As things go, while im spending money, just going super short seems the way to go.
