Ah. An E-type is a large project just to tune if it's a 12. If you want a straight swap that I'm sure wont' involve rewiring, replacing the exhaust and intake systems, and all that, then look for a TT600 or S4 motor. I don't know if Sagem injection will work with a D6 or D650 motor, nor do I know what kinds of bushings or other mods you might have to make or not make to fit one of those motors into the frame. I'm sure you would have to swap the header to get the best power.
It's a squid thing. You wouldn't understand.
Go soothingly on the grease mud, as there lurks the skid demon.
