What did you do to your truck today.The 3rd chapter

[Rich72C10]

Well, new toy / upgrade .... a Progression Ignition! I was a bit apprehensive but it went pretty smooth. Well, other than putting my plug wires on off by one plug on the cap - doh!

After following (and watching a YouTube) she fired right up at 10 BTDC. I didn't need to touch a thing (other than my wires). I have to say I get hypnotize watching the little red dot move around. I have a windshield mount for my iPhone and it is awesome watching all the data during test driving.

The other part of getting this thing is the lockout, which you enable/disable from your phone. After catching some guy trying to open my driver's door in the parking lot of Target, I'll feel a bit better being able to lockout the ignition.

On a sadder note, my newly rebuilt '72 carb crapped out on me yesterday and I had to put back on my '78 carb. I swear I can't win with that '72 carb. Something funky happen after nailing the pedal and just won't run right (like it is dumping gas, making a ton of black smoke, and hardly will idle).

'72 Carb is back on, Cliff told me that I likely tighten my bolts to much and that was causing my secondaires to hang open a little. I had told him that I used a digital torque wrench to take them to 15 ft lbs, he responded don't do that and just hand snug them down.

I did this with my hand driver, she started right up with no apparent vacuum leaks. Doing a number of back and forth test drives on my boulevard (to be very close to my home garage) where I got more and more aggressive on the pedal - no problems at all. I figured I did 15~20 foot slams, carb didn't stick. Hope it stays that way!

All during this testing, I'm also watching my Progression Ignition app from my iPhone. Freaking awesome ignition / app!


PS: So nice for Cliff to respond on a Sunday - that guy is aces.


Edit:
New response just now after I reported the good news to Cliff - he responded again. Which makes a lot of sense now.

Not much work done this weekend. Did make a 300 mile round trip down to my fathers house and moved a few loads of rock and pavers in my 67. Great weather to enjoy the truck. Soon as I get my ac going I will be using this truck more often

Worked on brakes to get rid of front hop during braking. I could feel the brakes grabbing on/off if light pressure and barely moving. Jacked up rear and spinning rear tire I could feel brake grab and release during each revolution.

Had the drums turned and yep, out of round. Shop took material from about 1/3 of the circumference. More like half for the other side. Drums were new, so either I did it overheating them or crappy part from get go. Had the new rotors turned as well. All new friction material and hop is now gone!

Found some more awesome wiring.
The entire tail light harness is butt connector heaven.
Who makes a decent harness?

M&H. Can get it through GMC Pauls.

GMC Paul’s is where I got my tail light harness.

I got the drivers side door sorted. Was a little close near the top front corner, then adjusted the latch. Overall a real pain with the front fenders on but I got it done. Waiting on some door handle gaskets and new door relay to put the entire door back together and then tear the passengers aide down.

It's turning back into a truck, good progress!

Spent a few hours under my truck today changing the way the trans crossmember was installed.

When I first put the motor and trans in the crossmember was outside the frame rail and bolted to the rear mount pad on the transmission. I had to put in a 1.5 inch aluminum shim to line up the driveshaft.

I never liked it that way and finally got in there and figured out that I could flip it and use the mounting pad closer to the transmission pan. Now it lines up perfectly with no shim.

OCD, but seems better.

Gmc pauls site doesn't like my phone.

^^^^You are going to get sued for whiplash when you get that truck back together. Guys gonna be jerking their heads around for a better look and hurt themselves.

Was wondering why my truck started misfiring on my way home from NC . Think the 43ts were to cold for the engine . Engine uses no oil no smoke and never needs water . 5 out of the 8 were nasty

[Jiggers72-GMC]

Thanks guys, obviously I was not awake yet when I looked at the hooks, they are not like mine (1971) at all,
mine are like this

I have been installing the same kit and it seems to be going good. Hopefully when the time comes to fire it up and test it everything works as it should. Good luck on the install.

Pretty sure I found what’s causing the miss in my 68 327 . Exhaust valve number 5 cylinder don’t look right rocker sits way to high at TDC . My guess is wiped cam lobe and or valve recessed into the head

Bad lobe or sunken seat, or a combination of both.

My thoughts too . I'm going to pull the intake and heads next week see what I find . The engine has 40k on a rebuild .

Sending positive vibes your way!

Got a new air filter, while I wanted a K&N I was able to get this Spectre air filter from O'Riley's and insure it fit okay on my Qjet. Reviews are mixed and I could have gotten it a lot cheaper online but I don't mind being able to support my local O'Riley's store.

I also had an annoying mismatched back bumper bolt, it had a slightly different shape head and then it wasn't chrome and rusting. I ended up just getting a 4-pack of bumper chrome bolts. None of the ones I took off had lock washers. Now I don't have to look at that ugly rusty mismatched bolt! Nice and all shinny now :-)

I tell you what, the fun factor on driving my truck has increased immensely in the last few weeks. With the newly rebuilt carb, new Progression Ignition, moving the throttle cable's pivot point (on carburetor bracket), and my new filter I can just about take off sideways! It is very satisfying working on the truck and seeing, hearing, feeling positive results.

[Jiggers72-GMC]

Great work guys, love the progress pics,
