Factory Tach

[slowburb]

Did any 73-78 trucks come with factory tachs and if they did what did they receive their signal from. I have a 71 350 with the older distributor and crane fireball ignition so if they ran off of the HEI I am out of luck.

I am trying to keep the inside original and have managed to tuck away some smaller guages and do not want to have a tach mounted in plain sight. Any suggestions would be appreciated.


Thanks

'73-78 did come from factory with tachs (as an option, not too many were opted that way, I wouldn't say it's rare, but it's definatly not common). '75 up came with HEI and that's where tach hooks to. If no HEI, just hook to negative side of coil, IIRC (that's all the HEI tach pin is)

my 79 came with a factory tach, you can usually find them on ebay, but they don't go for anything less than $100 even in non working condition

I got my complete gauge cluster with tach for $85 shipped off of ebay. The tach was off but I had it repaired and changed to a 7K tach for $40 from a guy on 69-72 chevy board. Works flawlessly now.
