Re: Attempting my first build 72 K5

Fired the motor up and she's alive and breathing. I let run for about 2 minutes. I'm hoping my friend can make it over to help me set the timing. I want to get that dialed in right away.

Here's a video of me starting the motor.

Re: Attempting my first build 72 K5

If this motor doesn't have roller lifters, you need to stop starting it up for theses short periods and. You need to start it up and get the rpm's up to 2000 and keep it there for 20 minutes, or you will flatten that cam. Continued short runs won't allow the break in lube to do its job on the lobes. That first start up is critical to the longivity of a flat tapper cam.

Not to speak for Mike but pretty sure he went with a roller set up.

Re: Attempting my first build 72 K5

Figured out why the e-pump would receive power as soon as I connected the battery.. I removed one of the red wires, the one I had going from the pump to the battery.

I now have it setup like this:

Positive wire from e-pump to switch
Red power supply wire from positive battery terminal to switch
Ground for pump
Ground for switch.

Now I got to go hide this switch somewhere only I know

Re: Attempting my first build 72 K5

A family friend of ours has been a mechanic for 50 years and he's been my go to for any kind of trouble shooting over the phone. He was supposed to come over today to help me bleed the brakes and set the timing, but he had a few things come up. Hoping he can make it tomorrow.

There's a local car show happening October 15th, less than a mile from my house. It's at the Santa Cruz Harbor and I plan to debut it there.

It would be safe to say the list of things I need to get done is now a short list.. I'm down from 3 white boards to only half of one.

That damn Horn relay as been lingering for a while. I don't think that's the right description for what I need to do. The horn closest to the fender originally had a plastic housing connector ( I still have it but took the terminal out of it) that used a two spade type terminal. the connector plugged into the horn closest to the fender and it used double spade terminal to feed the other horn.

Been searching everywhere for this kind of terminal but no luck

Here's where I was 8/14. I had three white boards filled back in the middle of June when I first got her back from paint.
