Well I sold my truck and bought another, yay! It's a 91 chevy blazer, 2 door, 2wd, 4.3 v-6, 5 speed. It's in almost perfect condition, which is a pretty rare find around here. However, it does have a bad motor, boo! Luckly my uncle is a mechanic and ownes his own shop so I get to use a bay pretty much anytime I want. I pulled the motor today, and tomorrow I'm picking up a used one to rebuild. Hopefully I'll have it up and running this weeking, wish me luck!

Here's some pictures of it. Page two ownes!

Sounds like a sweet deal. I want to find a 5 speed for my blazer. I also want to drop in a 350, but we can all dream. Maybe instead of putting in another 4.3, you should put in a 350 crate??? They fit in the 2wd's pretty easily i hear

edit: WOW, did it throw a rod?!?! That's some serious damage to the oil pan!

Yeah, that is a rod dangling out of the block... I thought about a 350 tbi engine, it wouldnt be to much more work, but I decided against it. I am going to pick up an extra 4.3 motor to rebuild (bore the block 30 over, vortec heads, intake, 454 thottle body, cam etc).

Have you googled it? It really doesnt seem that bad. I would look into that before spending the money on a 4.3.
There are a few good sites out there, describing how to do it, but i dont remember them.

350 bad gas 4.3 worse gas... lol here is my rule no replacement for displacement...
262<350 go with the 350

Cliff notes:

I like the thought of a v-8, but its simply not going to happen.

I've had good look with the 4.3's, so thats what I'm going to stick with.

I can get another 4.3 and rebuilt it as I have time, when I finish it I can pull the blazer in the garage and spend A DAY swapping motors.

A v-8 isnt practical for me right now, plus I like the thought of having a mean v-6, it puts a smile on my face. Plus my cousin just bought a v-6 blazer, we are having a little contest to see who can get their v-6 the fastest (I'll win).

Thats about it... :happy055:

I picked up the new/used 4.3 today. Tomorrow I'm going to pull the intake, heads and oil pan to inspect things. If everything appears to be good I'm going to clean it all up and put it back together with new gaskets and seals. I also plan to replace the freeze plugs, valve seals, and maybe the valve guides depending on how the look. This is surpose to be a good running motor so I hope thats all I'm going to have to do. Blah, this motor only has to last until summer anyways.

Anyways, here are some pictures of the new and dirty motor.

I pulled the motor apart, the only bad thing I found was the valve guides and seals, needless to say the heads are at the machine shop right now getting completely redone. It looks like somebody bought a rebuilt short block and reused these heads because the bottom end is in really good shape, so basically when the heads get back I should have a really good motor... yay!

The heads should be done wednesday and I hope to have it running around thursday or friday. :excited:

Here are some pictures of the motor as it sits now.

It got turned upside so thats why its all oilly. The cyl walls look dirty/pitted in the pictures but they arent. I plan to clean and degreese the engine and accessories as well as change all the seals, gaskets and freeze plugs before reinstalling the engine.

Hey...its missing 2 cylinders..

Just kidding. Should be a pretty nice motor when you're done.
