Most electric tachs have a, power wire, ground wire, and a sensing wire to the negative post on the coil. you might not have 12volt power to your dash causing all your gauge issues.

Thanks for the replies. The dogs name is Pokie. She’s a sweetheart. Whenever I start up anything loud, car, tractor or whatever she runs the 1/4 mile to my house. She a real gear head. The car is a 70 that I bought in 1980. It’s got a narrowed rear end and a 426 hemi with an 8-71 blower. Goes like **** in a strait line, good around corners? not so much.

Thanks

You guys are overlooking the true craftsmanship that went into the exhaust fabrication so it can pass local emissions test.

Hard to see but should be stamped into the end of the splined shaft in two places and one arrow or dot on the arm. clean it good with a wire wheel on a grinder if you have one. They are not stamped very deep but usually you can see them.

Accumulator. Works just like the pressure tank on you house well.

They make cheap wheel spacers also that might give you enough clearance.

I bought an aftermarket set and ended up throwing them away then I bought a set from CIH and they fit perfectly. Came black so they needed paint and were waaaay too much money but by the time I gave up on the aftermarket ones I was so mad I didn’t care.

The shaft should have two marks on it. One is stamped with a 2 and the other a 3. Line up the mark on your arms with the 3 and you will be good. Looks in the picture like it’s not correct judging by arm angle

My opinion fix everything that needs work. You get that 806 back in good shape and it will last you the rest of your life.

The backer ring is a thin rubber washer that goes in the oring grove and takes up a little space and it makes your oring just a little tighter.

Your going to have to update to windows 10 eventually. Might as well do it now. resistance is futile.

I just use whatever the neighbors have.

I run mine at 175 and then have a regulator that I quick connect inline if I want lower pressure for any reason. its nice having the high psi for blowing things off and the impact guns actually have some power. Done it like this forever and never hurt anything.
