Vintage tach and HEI distributor.

[Lynn]

I would like to put a column mounted vintage tach on my Studebaker farm truck. I used a 76 vintage GM hei distributor.

Will a Sun Super Tach II work with the old GM HEI?

If not, what is a good choice?

BTW, this thing runs great. Can't believe the difference between the flat head six (90 hp) and a .020 over 350 Chevy. No special parts. Used a Crane roller cam, described as "Brute low end torque and HP, smooth idle, daily usage, towing, economy, also mild turbocharged, 2200- 3000 cruise RPM, 8.0 to 9.5 compression ratio advised." Part no. HR- 260- 2- 12 IG with 72 cc truck heads, flat top hyper pistons, and a two barrel. 19 inches of vac., rock solid idle. 12 degrees initial, 36 total in about 3500 rpm, later than a light car would need... wanted to make sure it didn't ping when loaded. After all this truck, although it only weighs about 4500 lbs. has a GVW of 14,000 lbs.

Used a control panel to run idiot lights off the engine, and for ignition and fuel pump. Wanted an electric fuel pump as it may sit a few weeks, and that way, I just turn on the fuel pump and let if fill the carb instead of cranking for 20 seconds. Also, by running thosee things separately, I can more easily split the electrical for the horn and fuel gauge which are still six volt (so they go through an adapter 12 volt to 6).
