Let's remember Mick C went to fit an E-model gearbox into his C-model and found that the output shaft places the sprocket further out in order to clear the E's fatter rear wheel (6.0" vs the C's 5.5").
That's one problem... the top engine mounts *might* be another; they might've gone to thicker bolts on the E to give the frame more stiffness.
The zorst will definitely be a problem; the E-model went to wider headers, with wider exhaust port exits, so the C-model pipe won't fit.
As for the 'letrics... I think so long as a C-model ignition rotor (with 4 trigger points) was substituted for the E-model one (16 triggers), the existing ECU and ignition system should be able to cope.
