You might be able to get a gas tach to work on a 6.5. If you put a HEI where the vacuum pump goes and run an ignition+ wire, then you'll have a tach signal to run to the gauge cluster. Of course you'll be missing a vac pump. I had an aftermarket diesel tach that had a pick up hose clamped to the alternator, might be an easier way to go.

Look at Chevy C60 and C70's. They have the 4k and 5K tachs. The upper is the diesel as it has the 150 LBS air pressure gauge.

Shoot me a PM with your price you think is fair plus shipping. If you want I can throw in a vacuum gauge as well. I don't have the cluster anymore, just the gauges.
