ZZ4 Engine Temp Sending Unit

[JE Caudle]

Howde hi friends and neighbors,

Anybody know which Temp Sending Unit will fit the Fastburn 385 heads?
The sending unit I pulled out of my '78 L-82 is way too large!

Thanks in advance!

It is a specialty item, the old gauges in our sharks take a resistance on the sending unit that is Not made in the small size to fit modern heads....

so you get to spend a ton of bux, or do what I did, recalibrate the gauge to make it accurate as hell around the temps of interest.....

I forget the R values I used, but I could use a L98 sender, and get it to track really good between 160 and 240f......i'ts not all that hard to do, just need to get the two ribbon resistors off the back of the gauge, and rig one in series and another in parallel with the sender and gauge.....

I did mine years ago, before there was an commercial 'fix' for the problem..
