I set it at zero at the top. The way it was explained, deflection to to the right of zero was negative and to the left of zero was positive. All of my deflections were to the right. As the tech in the video explained (and assuming he is correct), I would need to move the bellhousing downward to get it within tolerances. I only took readings every 90 degrees not at 45 degrees.

I guess I need to check that after reading all of tonights posts. The service manual shows (chronologically) checking the bore first and then parallel so I didn't give it much thought until tonight. The video did the same.

Well mine changed when I shimmed it. I have washers that are precision shims, they are .006 thick. If you need a few PM me and I will try and get them out to you in the mail. tim

The bell housing needs to be attached with all of it's fasteners & torqued properly before checking runout and squareness. It makes a BIG difference!!!!!
All mating surfaces should be bare metal with no burrs
If you ever wonder why some cars are faster than others...it's in the details....
I couldn't believe how much paint was on both surfaces when I went to put them together. It all adds up. I scraped them down and just barely dusted the bellhousing and block plate with paint and a little light grease on the block so they wouldn't rust.

Checked the bellhousing for parallel yesterday. I had a hard time getting consistent readings so I had to change the set up a couple times. Must have checked it at least 6 times when it was all said and done. In the end, the greatest total run out I had was .005. The shop manual says to make corrections if total run out is.006 or greater. Now I am just waiting for my offset dowels which are scheduled to be here tomorrow. Hopefully I can have this wrapped up and in the car this weekend or early next week.

I have been thinking again on the alignment question also. I don't see that the block surface would be off at all. As for the bell housing, maybe the stock aluminum might be contorted after 40 years and have either block facing or the transmission facing out of whack. I have the tools to check it but ain't gona do it. Indexing the center is good enough.
Why wouldn't the block surface be affected after X thousands of heat cycles the same way the cam tunnel , the main line and the head deck surfaces are ?

Finally got my offset dowels. I had a hell of a time getting one of the old ones out but finally won that battle. Installed the dowels so that the bell housing moved downward .007 and my runout was no more than .002 top to bottom and within .001 side to side.
Thanks for all the help!!! Now I can bolt the tranny up and get the engine in the car....I think...

ok, my turn. i set the dial indicator and then turned the crank 90 deg each time. set the indicator at 0 at 6:00, and these were my readings the first time around:
0 .014 .001 -.012
did the setup again for out of round and got:
0 .012 .002 -.013
so, i have some .007 offset dowels. do i wait and get some .014's or do i just go for the .007? that will put me within range. FSM says .008, and the Robmc dowels I have say .010.
what would you do?
Okay, if I understand what you did, bottom = 0, left = .012, top= .002, right = -.013. TIR vertically is 0.002, off center is 0.001, no change necessary. TIR horizontally is .025, off center is .0125. The 0.014 dowels would get you within about 0.0015 off center, the 0.010 dowels within about .0025 off center. I'd use the 0.014 choice. But I'm anal.

i think anality wins out here. i agree. i may as well go for it and get it as close as possible, and yes, if i also understand things correctly, what you have stated above is correct.
well, only one more week while i wait for parts!
until the next snafu, that is!
