6 cyl. tach in v8 conversion

[catfishdb]

I have the original Jaeger 6 cyl. tach in my 2500m. The engine is now a 302 Ford unit. Is there a way to keep the original tach but have it read the v8 rpms correctly?

Thanks,

Thanks guys,

If Bernard had not come up with the info about Nisonger Instruments I might have tried to ship it back to England. Thanks anyway Andrew.
I will have a look at the tach when I get the car back this weekend Andy but I wonder if this is the case with mine. It is labelled on the face 6 cyl.

I will give Nisonger Instruments a call in the morning to see what they might be able to do Bernard.

When I blip the throttle to down shift the needle swings around quickly to 7-8000 rpm. It is getting interference of some kind I believe. With the idle set at 750-800 rpm the tach shows roughly 1200 to 1400 rpm.

Just to be safe I have a rev limiter set at 5000rpm. I have not hit it yet. The noise at present is immense.

I love this forum. So many options for what I figured might be possible but was not certain. I am going to get this sorted and will report back.
Looks like this weekend might be clear of rain so no hope of working on the car other than driving it. New tires being fitted as we speak.

Thanks everyone,

Arthur
