Welcome, Nice rig!
Hello again to all! I didn’t realize it has been nearly 4yrs since I last worked on this truck. I moved away for a couple of years with work, but have since transferred back and now finally able to start bringing this project back to life.
I finally broke the ice and pulled/tore down my first motor this weekend. This motor ran good but I’ve been chomping at the bit to do this for years. By no means am I a mechanic, however I have wrenched a little here and there over the years. I wanted to do it myself to learn a little bit along the way and also work on the same motor that my grandfather once tuned as well. Overall everything went smooth, however splitting the Tcase (attempting to keep it from smashing to the ground) from the transmission before pulling the motor/trans was definitely a pain in the a**! I got it though with the help from a work buddy and we both still have all limbs attached.
Just getting started:
3970010 casting # on block.. cracked open the oil pan and was pleased to see this:
Loaded up and taking to the machine shop in the morning to add a little pep in her step
Can anyone give me any information on the transmission and TCase? I’ve seen literature on GMSB before but can’t recall where I found it.
Trans pics: I apologize but I can’t figure out how to post pics that are not rotated sideways ♂️
Random pics of truck:
Damn those bumpers mean business!
What are your plans for the engine?
As of now having it bored, hot cam, new carb, aluminum intake, headers..
Yes the bumpers were on the truck when my grandfather purchased it years ago.. they are 1/8” plate I believe. Definitely solid lol!
The trans is an SM465 with a 10 spline output and "figure 8" style NP205 transfer case, with a 10 spline input. That combo would be from a '79 or older truck, or possibly also an '80-'84 K30 crew cab (no slip yoke).
Welcome back. Sounds like you've got a good plan started.
