Engine Reversal and EFI

[Bruce Bowling]

~ (1) The crankshaft rotation (and hence firing order) must be reversed
~ (thought the camshaft and distributor rotation is preserved).  Would this
~ preclude using the stock fuel injection system (either TBI or CMFI)?  If so,
~ are there workarounds?

I would think that all you have to do is follow the new firing order
(ignition, etc).  If the EFI uses any type of crank sensor wheel which
also synchronizes the system, it will have to be flipped.

~ 
~ (2) The Corvair speedometer is driven by a cable turned by a front wheel.
~ Can this, through appropriate gearing, be used for a vehicle speed sensor?

This should work.  If memory recalls, the Chevy setup wants 1000 pulses
per mile.

~ 
~ (3) 1993 and later computers also interface with the transmission.  Since
~ I'm going to use the Corvair transmission, how should I terminate the unused
~ terminals (i.e., leave open, ground, ground through resistance)?
~ 

If the old transmission was just and overdrive tranny with a lockup
converter (e.g. 700R4, etc), the wires only control the converter.
So you can leave the wires hanging in this case.  Anything else
I am not sure of.
