Is it hanging on the dowels, exactly where it needs to be when the bellhousing bolts up?
Or is it pinched?

 

I haven't even gotten to that step yet...I just put the fly back on...snuged-up bolts...went to torque the bolts down and needed to turn the fly for clearance (from balancer) and it wouldn't turn.

 

Doesn't the plate go on BEFORE the flywheel?

I know it sounds stupid, but do you have the flywheel facing the right way?

 

The block plate does go on firsta nd then the fly...smooth side of fly is facing towards the trans.

The few people I've talked to I know who are wrenches...keep telling the fly bolts are too long and preventing the crank from turning, but their the factory bolts that have been in the truck all along...I'm thinking a couple of the bolts require washers on the backside...?

 

Yes, you said before, you are using the same bolts that came off.

I've only ever seen a washer on a flexplate bolt, never a flywheel bolt.

How can you bolt up the flywheel without the plate in place, if it goes on first?

 

The plate has to be in position.
There should be locating dowels in the back of the block.
Hang the plate on the dowels and THEN bolt the flywheel up.

99% this is your problem.

 

First, let me thank you for your time on this...The block plate is on first (up against the block), but you could bolt the fly to the crank without it.

 

Okay.
The plate on most engines would never fit over the flywheel.
IDKA 4.9's...

 

I just don't see what would prevent the crank from turning completely...there is no dragging...metal hitting metal sound, etc...its just locked-up.

 

Is the plate free to move... bang around???
If it's in front of the dowels, it is pinched by the flywheel.

Like KS said, loosen/remove the flywheel and see what's up.

 

There is two dowels coming from the block, that the block plate goes on...I will check and see if it slipped off, etc while putting the fly on.

Also, my book says to torque the fly bolts between 54-64lbs/correct?

 

Just take the dang thing off and figure out what happened, all this speculating is just a lot of self-imposed drama.

 

I'm not a mechanic, just a guy who may be is a bit more mechanically inclined then some. Also, s I'm working on my back in a cold parking lot w/little to no-clearance...I wanted to troubleshoot a bit, so I know what to look for LOL

 

I'll bet a "cold" parking lot to you is 70°F or colder.
Just playin' with ya

 

Cold enough...30's in the mornings
