Well, Monday night I got the whole back end stripped down and cleaned up as best I could with a vacuum. Someone decided to cut a hole in the bed to swap out the sending unit in the tank so I will need to get a patch panel for that (junkyard). I also got the passenger seat out and floor stripped down. The seats were not original and there are quite a few extra holes in the floor that I will need to weld up before I am all said and done, but all in all it is quite clean. Surface rust is all that is there.
Instead of putting carpet down inside, I think I am just going to throw down some bed liner on both sides of the floor (inside and underside) and call it a day. That way I will not have to do anything but prime and cover with bed liner!
I was able to partially identify the motor as well, details of which can be found on the Drivetrain page. Since it is a car engine, I am not sure if it will be a 4-bolt main. I may just build up my other engine and drop it in, then do something else with this one… Not sure yet.
Other bad news is that none of the seats are original. The back seat looks to have come from another Blazer so that is good, but the front seats are from something different entirely.
Here are some pics of the progress from Monday night: 


Last night I did a carb cleaning and general tune up. I did not mess with the plugs or wires, but I adjusted the timing and carb jets so it was running better. Started it this morning (38*F outside), fired right off with no pumping of the pedal, and it sat up on the high idle for a few seconds. Tweaked the throttle and it dropped down to normal idle and stayed.
Now I need to get an HEI distributor for this thing. I will not mess around with points. For the time being, I will probably just steal the distributor from my Chevelle.
Looks like you are doing a great job on your project , we have a f150 that we have been working on ,takes alot of work and time . But the work is are pride .
Thanks!
I have too many things going on right now, but I just got heat in my garage at home so the Blazer is getting some TLC. I am currently fitting the exhaust, but I may have to stop half way through that to rewire the ceiling in the garage properly before laying in some insulation.
