what's the cost of a new 7A, even available? cheaper than 20vt swap or more?

New, "crate" 7A? You may be able to get one, but I suspect it would be cheaper, and more timely to rebuild a decent existing one.
Thats what I was going to do with mine, until we pulled the head, and saw some not nice things WRT the block...I had picked up a good used bare long block for fairly cheap, but then got the turbo bug, and picked up a 10vt donor car. Sold the 7A short block to a fellow AW'er, who has put it to good use ;-)

Re: what's should I expect to pay a good shop to rebuild my motor?
7A's are fairly expensive to rebuild, expect to pay up to around $800 for all the parts for a total rebuild. There is also a good deal of time involved, perhaps a week if its the only thing they are working on...Some of your original bits will need minor machine work. New wrist pin bushes need pressed in, then reamed to match the old pins. Cylinder bores will have to be cleaned up (measured for roundness and uniformity, then deridged and honed if it passes inspection). You'll also want the blocked totally stripped and cleaned, tanked, painted. Head should be stripped, cam journals checked for wear (they are NOT replaceable, and usually stay w/in spec), new valve guides pressed in and reamed to match the existing valves, new valve seats cut, etc etc. Whole lotta work to do it right.
But, once its done right, you can expect another several hundred miles out of the thing, even if you have things done like new (more aggressive) cams installed, milled/shaved deck height to raise compression (better run premium), new higher CR pistons, different rods, etc. Doing that stuff is when it gets really expensive to rebuild a 7A.
