@Chris64 you did bypass/eliminate the resistor wire and give the HEI a good solid 12v right?

That’s something that is often overlooked doing an HEI upgrade, they will work being under volted for a while, but issues will arise at some point.

Got 6 new tires for the '76. Painful, but they'll probably outlast me. Lol

Installed a shifter by using 1” tubing bolted to seat frame so not to put holes in my new carpet. Extra long cable so it goes through firewall. Two bolts and undo cable and it can be removed leaving the cab stock. I race the truck in the NHRA Sportsman class so that is why the shifter, column shift with no safety stops for hitting neutral or reverse was a concern.

I worked on my '87 & it's not perfect but it's good! Considering it was almost 40 years old with mostly original paint, I've given the next owner a much better guide coat than what I started with.
Your ride looks great, put the adornments back on & go ride!

I did do the sanding/wet sanding today. Rubbing compound and polish next. This chit is for a much younger person. Following this guy's plan from the SPI forum (mostly)

Oil pressure sending unit in my blazer, oil pressure gauge was not reading well. Did oil pressure test which I did have and the sending unit was bad, the 5.3. Did notice an oil leak too coming from it

Nice long weekend to put in a Edelbrock Performer intake and general top half clean up. I also replaced a leaking freeze plug. NOT Fun. Not hard, just very difficult to get to. I have to get the rest done since one failed.
She runs well. Timing set to 10 degrees BTDC. New tach will be here Wednesday to help set the carb.
Next in line is fuel tank replacement. The PO included a new tank and sending unit. It would be nice to know how much gas I have in the tank. I can get rid of the jug I have been carrying around for when I run out.
When warm she only has around 15 psi of oil pressure at idle, jumps to 30 by the time I hit 800 to 1k RPM. Then nudges higher with more RPMs.
