What kind of mileage are you seeing?
Did you use all the stock gauges on the dash?

Very nice install! How was it to drive? Enough power?
Did you use the Merc transmission?

Still breaking the new engine in, but getting in the high 20's in fuel mileage. Using all the gauges but the tach, still working on a sender for that.

Nice. Do you have axle ratios from a manual Comanche (3,07)?
If this was originally a 4.0, the tacho seems to need symmetrical square wave signal. When I did my Cherokee OM605 conversion I did it like this with a universal hall sender (3 taps as 6 cyl fires 3 times per rev), but tacho revs went crazy on higher revs. Then I made a circuit which delays the ON-pulses to make more symmetrical square wave and that helped. It would be easier to make the wheel so that gaps and elevations would be equally long and equally spaced.
