swap a B230F for a B21A...? 200 1978

Answers:

not very, although it is a couple of days work depending on the standards you set yourself for workmanship. The most difficult part would be the intact extraction of the '86 wiring, sensors and electronics and transplanting them into the '78.

Performance: should be better. Of course it depends on what you call marked difference... Economy: probably not very much, the B21 isn't too bad itself.

It would definately be easier.

I would expect so, but haven't done this swap myself. You'ld need to check the figures on advance/retard for both, transfer the distributor and control box, and check from where it gets its signal and transfer that sensor (if any, and possibly flywheel) as well.
