Well spent all day getting ready to install the trans. it is in the car with all the converter bolts tight and all the trans to engine bolts in with the bell housing sitting about an 1/8th of and inch away from the engine the motor tuns over by hand but I hear some scraping sounds. when i go to start tightening all the bolts it locks up the motor. The converter is seated all the way in and I know that for sure. the sound is like the converter bolts are scraping up against the plate between the engine and tranny. any help or suggestions would be great.

No problems with the motor plate making noise before? You could ask someone to turn it over by hand while your under the car. That way you can feel for were the contact is coming from exactly. I had a similar problem once were if I pushed the stall into far, it would lock up. Unfortunately I never finished that project, so I don't kow what is was.
tightened the bellhousing bolts first. then it wouldn't turn over then loosend them up about an 1/8th of and inch and put the converter bolts on then tried thightening again and it locked up once more had a friend come over and turn the motor over while I looked at it and then put some white marker on the converter studs and spun the motor over and the white mark is gone when the studs come back by. I'm frustrated with this I wanted to take the thing out for a road trip on new years eve and this trans issue is starting to get to me.
what seems to be happening is that when the bellhousing is tightened up the stups on the converter are hitting the plate in between the engine and trans. I can now see where they are scraping. can I grind the studs down about a 1/16th of an inch or would I be shooting myself in the foot? I did tighten the bellhousing down first and then it locked up the engine. I only loosend it enough to turn the motor over.
I'm about ready to just have the original tranny rebuilt and use it and take my loss on this one. The original tranny is locked out of drive it shifts into park reverse and neutrel but then stops.

It sounds like you've run into one of the common auto tranny installation problems. It is very important to get the converter to completely seat on the tranny, otherwise you will have the exact problem you're currently experiencing. This is trickier than it sounds as you're supposed to seat it until it clicks down twice. I've done a number of these and almost always have to pull it off and reseat it a few times before I feel confident it really is seated correctly.
Hope this helps...

Sounds like DarkBuddha is correct. I've done the same thing. Actually, I had it seated and it came loose while I was wrestling the tranny into place. It helps to have another hand down there ro hold the convertor in placw with a screwdriver for as long as possible. Seat the convertor by rotating back and forth while applying pressure until it clicks a couple of times.

if you crawl under the car, you will see the balancer on the flexplate all scraped up, this is what is hitting, not the bolts. it is hitting on the bottom of the dust shield plate. just take a big screw driver or prybar and bend the bottom of the plate out. This exact same thing happened on the roller conversion for my car. first start up it was alot of banging, thought the heads were fixina lose all their valves and blow the motor. after probing around listening to the heads, they were fine. Turned off the motor and noticed the balancer at the bottom of the flexplate was the same blue the backside of the flexplate was. Bent it with a screwdriver and had a nice silent motor.
hope this is your problem, from your post, it sure sounds like it...

Torque converters not seated. Everones been down that road somewhat.
You're obiously putting so much pressure on the T/C that the flex plate is well, flexing forward.

Here's one I did once--make sure the torque converter and flexplate are matched--I mean does the drain plug for the torque converter show through the hole in the flex plate? If not, it is 90 degrees out. You have to pull the trans out again, rotate the converter 90 degrees and reinstall the whole works. I did this once and the motor would turn but made a squeeking/scraping sound. I also did the TC not seated properly once and the motor would not turn once the tranny was bolted up. (I screw up a lot as you can see... 
)
Given that your motor turns, I would start by looking to see if you can find the drain plug on the torque converter. Good luck.

I can relate but you have me beat! I was putting in a new engine, pulled the converter to put in a new seal. Had the motor in and out of my 4x4 F150 6 times that day before I figured it out. Working by myself of course! DOH!!! Glad that is over!
