The main axle nut at the hub? 34mm. Should be the same for both.

Ok here are some pics of the motor and park ave. I know y'all can't tell if it worth it, but just give your honest opinion.

As i look at this pic I forgot to look over the front of the subfram. :( Will a 92+ Non */c one work if this one is bad?

Also I believe the computer is gone, but maybe i was not looking in the right spot.

Yup, the PCM left many moons ago, or at the very least, before you got to it

I have to ask if you happen to know the mileage of the engine/transmission. I also have to ask if that PA had any body damage to it severe enough to render it totaled. There is a good reason why I am asking this. If there is no damage at all to the body (and I am not talking about missing body panels), assume either the engine went, or the trans did. And most L67s have digital odometers (though I think the PA is analog at that time), so unless the yard recorded the incoming mileage, determining the true mileage is impossible unless they let you hook a battery to it.

But, the head looks pretty promising. Demographics play a large part as well. Most Buick owners are older, more mature, and more likely to follow the maintainance schedule than the rest of us folk.

Your best bet, if you get both the engine and trans, is to core/rebuild them before installing. More money in the long run, but well worth the effort.

That front trans mount is blown. Probably happened when it got T-boned.

How long has it been sitting? I don't like the rust on the pulleys, but then again, that may just be rust on the pulleys. If you know what I mean.

You'll definitely need a PCM. You have the right connectors there in your hand (pic above).

Al 92-99 H bodies have that EBCM (brake thingy).

Ahh....

Still, with those miles, I would be cautious installing them as-is. S1s have a bad habit of spinning rod bearings around the 160k mark, regardless of how well they were treated (though the 94-95 models have an improved bearing design).

Though I admit, that engine does look good from the pics

I have all of next week off, I think i'm gonna do it. If the motor does crap out I will be ready for a 3800 II */c. My plan is to pull the motor and trans and cv axles. Replace the oil pan gasket, put a new timing chain on it, change the */c oil, and other little stuff i can do with the motor out the car. Using a engine puller I will jack the front of my car up to remove the subframe. I will use my old suspension so that will drop the price of the sub frame to 57.40, and the Cv axles will be $28 each.

So all and all
Motor $140 (W/o core)
Tranny $55 (W/o core)
Subframe $57
Cv Axles $56
Tranny Cooler $7
Random parts $50
grand total of $365 (Like that price)

but what other computers can work with this motor. Can any 92-96 3800 */c computer work?

(think of me as a cheap a$$ SOB, i will cut corners if i can. "with in reason")

Hmmm.

With that setup, you are limited to the 94/95 PCM. I am trying to work out an idea using the OBD2 computer on the Series 1 L67, and should work in theory. The biggest issue I am having isn't even tuning related...it'* in grafting the newer PCM harness to the older wiring. To see what all is involved so far (and I have put it on hold until I finish up with another members car):

http://www.bonnevilleclub.com/forum/...highlight=obd2

Alot of work will be involved in doing this. I am finding more things to take into consideration the more I talk to other members. Not necessarily bad, but I will need to design in workarounds, or live without some features.
