Question: Digital tach conversion on a C3

[jw15870]

Just dropped in a fresh 383 stroker that was outfitted with a MSD distributor and 6A ignition control. The C3 has a mechanical Tach. Anyone else tried to convert their gauges over? Is there a digital tach option available that matches my existing '73 gauges or am I looking at having to convert everything?

I think you mean 'electronic' tach not 'digital'. These came standard on '75 and up Corvettes, but I'd speak to the engine builder and find out why he didn't simply supply a mechanical tach drive distributor for your car.

MSD makes a tach drive distributor. Its the 1st thing on my"want list". Maybe you can see if you can exchange yours.

I've seen those, but don't think they work with the ignition control. The electronic systems put out much more spark, so I wanted to stay with it.

The MSD tach drive dist. is exactly the same as the one you have now but with a provision for the tach drive cable. It will require the 6A box you have already to work.
