Also, before the latest test drive a "tractor-like" chugging sound along with some louder air sucking noises developed from the engine which appeared to be a blown manifold gasket. We removed the manifold and found that the fiber-style gasket (installed not that long ago when the engine was changed) was in pretty bad shape. We guessed this was used instead of the better metal gasket because the cheaper type come in the kit? Anyway, metal gasket has now solved these problems which we noticed AFTER the primary trouble, so it's not likely THAT was the cause of the sputtering/won't-go problem.
Won't be able to update again for a few days but will not forget my promises to keep you posted so hopefully all will know what WAS the problem, those of you with similar troubles can try THAT fix...and somebody will get the prize they deserve.

Did you check for "flatness" of the manifold? I understand that sometimes you need to mill down the manifold to assure it is not warped or not flat. Just a comment I have read so I am no expert on this subject.
