Your balancer isn't fully seated... The back side of the balancer should just barely clear the timing cover. From the face of the block to the outer edge of the V-belt groove should be just under 1 1/2" for your vintage SBC with a metal timig cover (the L31 plastic timing cover is different). If you look close at this pic, you can see it is at 1 1/2" and still has about 1/16" of clearance between the balancer and the timing gear.
Another way to check is to remove the balancer bolt and look at the end of the crankshaft. It should be about 1/8 to 3/16" below the recessed portion of the balancer... very similar to this pic:
Just make sure you check for rubbing on the back side...
It also appears that you did not shift the tranny mounts over about 1/2 - 3/4" or your engine/tranny is mounted too far to the rear of the chassis. An Archie SBC/Getrag (or isuzu/4 speed) will fit w/o any need to modify the frame rails. It is just a matter of properly positioning it and getting the balancer as tight to the engine as possible. I have even made an L31 timing with its protruding cranks sensor work w/o modification to the rails (but it requires some clearancing work to the balancer).[This message has been edited by fieroguru (edited 01-17-2011).]

There he is! 
That car is coming along great.  Some nice detail work, and an awesome writeup. I can tell that you really enjoy being out in the garage. And you must have a wonderful woman at your side for dealing with the obsession.  (Do they ever get the recognition that many deserve for putting up with us? I think not.)

Thats what I was thinking. I have about 1/8 of an inch from the back of the balancer to the timing chain cover.

Thanks Guru! - I'll take some measurements this evening and see where I am at. I suspect the balancer is not "seated". Whaer I have some confusion is that this car had a SBC in it when I got it and there were no clearance issues with it although the frame rail had been "poorly" hacked up. I added some reinforcement but did not come out past the frame rail to the inside at all. I'll have to look at it a little closer but I think I can slot the trans mounts and move the motor 1/4 to 3/8" towards the driver side. I just can't find the difference between this motor and the one that was in it. Hope it's the balancer but clearnace behind it and the timing coever is looking pretty tight. Thanks again for the reply and tips.

Yes Tony, She is a saint! But actually I think she prefers that I "hang out" in the garage and tinker with my cars - that way, I am not in her way and she always knows where to find me should she need the pickle jar opened and the leaky faucet fixed!

Fieroguru was right on the money. I was able to pull the balancer in further but I did have interference with the aftermarket timing cover. I dropped the rear of the cradle and pulled the balancer - it was not hitting hard - but enough to scrap the paint on the cover. I gave it a little "lite" adjustment with a watch hammer and reinstalled the balancer. Pulled it back down on the crank and all is good - I have plenty of frame clearance now!
Thanks Guru for your help!
You can see where the balancer was rubbing the cover!
More later!

Thanks Dan! Already have it back on. Just waiting for Summit to deliver some fittings for the pump. Still have a mix up on my order - should know more tomorrow! Motor is in, OP primed, Dizzy is in. Wired up, clutch master is back on with shift linkage. Just need to fab a crossover coolant tube and plumb it and she will be rady to fire. It's getting very close now. Thinking I'll take a couple vaca days when/if my pump fittings show up. Going to try and get the suspension/axles, etc reinstalled by tomorrow night.
More later!
