No pictures yet. I don't have room in the driveway to park it here so it's at a buddy's place for now. My dad had a '78 Blazer sitting out behind his house in Yakima for a couple years so I drove out there and took it off his hands! I was having some issues with the transfer case, it was stuck in low range. After steve and I played with it for an hour or so we got it to engage high. It's pretty much stock height, some random 31's on it, and a little droop in the rear.

It's "supposedly" got a 400/th350/np203 drivetrain but all I know about it is it's a 3 speed, so that meshes with the 350 part. I haven't had a chance to get block numbers or anything yet. Some random long tube headers, a carter AFB w/spacer and an edelbrock manifold. On the way over here it seemed like such a dog. I'd downshift it (it won't kickdown when you punch it) and it would seem to actually get slower. I've already priced out a simple 4" lift with shackle flip and plan on some 35s.

Sounds like fun. I like the big blazers.

Pictures. Gotta love the brown, hides the rust. Very Happy

The truck seems to run like junk and after I shut it off, it'll smoke out the carb for quite awhile. I don't know anything about tweaking carbs, is there a good place to start? The only thing I did was kick up the idle screw a bit because it kept wanting to die at idle. Although I don't have a tach (nor timing light, nor vacuum guage) yet so I don't know what it's sitting at.

Oh yeah, and anything other than perfectly level ground and it won't stay still in park. It'll just sit there rolling slowly and clicking really loud out the trans. Does that mean a new trans?

Ian, if your free this weekend I can swing by with my light and vac gauge and we can take a look at it.

What plans do you have for it? You getting rid of your other project Blazer?

Hell yeah you can swing by. I don't know jack about carbs. I work saturday but usually get off early because people think stealerships close early on sat and sunday I'm off.

I sold my other blazer awhile ago. Got more than I paid for it!

Plans are a 4" inch lift, trimming and 35's for this winter, eventually lockers, overdrive trans and efi. I use this to practice welding up bumpers and such too. Smile

looks like a fresh motor... or atleast fresh paint.

I like them removeable hardtop blazers! I just never cared much for that style front end.

Dude, kurfbird just took my Z28 off my hands and it has the same carb. He'd probably sell it cheap if you wanted another one.

Is that just a plain aluminum adapter under it? I had alot of trouble with that type of carb getting too much heat from the intake. It would cause the fuel to boil out of the carb when shut off, then be hard to start when the engine was warm. Several others around here had the same trouble. Cure was a phenolic spacer. Got rid of both problems.

You said it had been sitting awhile. The hei distributor has a habit of having the mechanical advance seizing up. Take the cap off, twist the rotor by hand.. it should move one direction, then spring back when you release it. If it doesnt you'll have to pull the distributor apart to clean and lube. Also check the vacuum advance. Usually do this by attaching it to manifold vacuum at idle and seeing if the timing changes.
