As some may remember, I bought this Blazer about 3 years ago and have been focusing on the 69 K20 so this one has sat waiting. I believe it hasn't been driven in about 9 years. I fired the motor up about 2 years ago and it gushed oil from the rear main seal. I was going to move the engine crossmember and replace the rear main seal with the engine installed but decided I would be time ahead to just pull the motor and have it looked at.

It is a 400 small block and for some reason someone put 62-64 327 heads on it with 60cc - I'm assuming those are probably choking the motor. I took the motor to an engine guy today and he is going to tear into it then give me a call to advise of the motors condition.

So now you are starting on this.Are you going to do a restoration like your k20 or just keep it like it is?Are you done with the k20?

Looking forward to seeing you tear into your Blazer Yukon. Keep us posted on your Buildup. Are there any Big plans for the Blazer or is it gonna be a trail rig?

Just want to get the Blazer road worthy and enjoy it. It will get a 4" lift done correctly (the PO used 73-up front springs) and just kind of clean it up. I don't plan on tearing this one down like I did the 69. That may happen in a few years.

And the 69 isn't really done yet, I still need to figure out a design for a front bumper and do a few other odds and ins on it.

My mind has been thinking of driving it without the top for too long and I just have to get it going!!!

You got that right. On the way to take the engine to the engine guy, my two girls went with me. My youngest Alexandra again mentioned how she couldn't wait for it to be running and then "I would have two cool trucks." Man, that girl knows the right things to say!!!!!

IF ONLY IT WAS THAT EASY TO HAVE THE MOTOR JUST JUMP OUT AT ME, WOULD SAVE ME ALMOST A WHOLE DAYS WORK, I am slow at mechanical things....

Yukon Jack 04-09-2006 05:14 PM

Re: I lifted the hood on the Blazer . . .
 
I got it out in 3 1/2 hours, which I didn't think was too bad considering this is the third motor I have ever pulled. I was expecting it to take much longer. Gotta love these old trucks!

I beat you there, I spent 1 hour pulling the front clip off of mine, then it only took an hour to snatch the engine (it's SO EASY with nothing in the way). So figure 2 hours total!:metal: Bet yours looks a lot better than mine going back in.;)

My problem is I always find things really easy to take apart... getting them back together has always been my problem :lol:

Re: I lifted the hood on the Blazer . . .
 
That is my problem too, I am making sure to do as little as possible to get this back on the road, this project has set too long for me to want to tear into it any more than necessary.

Just got off the phone with the engine guy - he said a rod was crumbled up a bit and did a little cylinder wall damage but should clean right up. He said it didn't look like the motor had been bored out before so that is great news. Most interesting, he said the oil gushing was due to the oil filter gasket getting pinched and folding up a little. That is interesting cause someone mentioned that in the past and when it gushed the first time, a few days later I pulled the oil filter to see if maybe an old gasket had stuck to the block, put the filter back on and it did the same thing.

Gave him the okay to get the motor in the machine shop for a 0.020 over bore to see if it cleans up of if they need to bore it out more. He should have it back from the machine shop in about 1 1/2 weeks and then he will be right on top of getting it put back together. Can't beat that!!!!! Vroooooom time before too long I hope!

Great news for sure, glad to hear your good fortune. :)

Mr. Vroom, it is.

Got out for a short amount of time last night. Messed with the transfer case a bit. I need to put in about a 1/2" spacer to drop it down. The crossmember I am using was for a Dana 20 and with the NP205 transfer case installed, it is rubbing on the bottom of the floor.

Next I started installing the front springs. I got these from Skyjacker's (edit - it was Superlift, not Skyjacker) scratch and dent store on e-bay for like $29.00 for the pair. They had no damage at all and although not the springs I would normally buy, for the price I couldn't pass them up. Had to pull out the metal bushing for the front of the spring eyelet and cut it down a little bit. After that, got the driver side to slide right in. Hopefully get out tonight and get the passenger side installed.

I think I will snatch a spare 350 I have lying around and drop it in the engine bay, then I can pull the old 12 bolt axle and put in the 14 bolt. With the engine in, I can then measure the rear driveshaft and also figure out the right angle for the new spring perches. Need to then get them welded on. I can also throw in the front driveshaft and make sure it is the right length.

Pics, sure I have pics. The first one shows how rediciously low I had to drop the front of the truck to get the engine out.

Next, here is the driverside 4" lift spring installed. I'm using Offroad Design's heavy duty rear shackles and greaseable bolts all around.

Re: I lifted the hood on the Blazer . . .
 
How much lift will the shackles give? I know that's not what they're for but i'm still wondering. I feel my blazer is ALMOST perfect, but it wouldnt hurt to have the inch and inch higher or so. Would those shackles do the trick? I've looked at them and thought it over before. Looking good, thanks.

Yukon Jack 04-14-2006 01:52 PM

Re: I lifted the hood on the Blazer . . .
 
They are just a 1/2" longer so only give you 1/4" of lift, they are just good in my opinion for added beef - plus I like the greaseable bolts.

do you have a link for that scratch and dent store you refered to?

dang 60CC 327 heads on a 400 that would make some compression for sure, what heads are you going to run? I have some 441 heads 76cc that would make a hell of a torque monster out of a 400 if your interested PM me.

The engine builder has some 882's that he is checking out to make sure they are good - he said they should work well on it.
