Went out and dug up the 3.40 pulley and a couple belts. The 43" inch belt should work if it's new, but if it streches much, you will run out of tensioner travel, and the tensioner could end up against the blower pulley. The 42" belt should work fine.
One thing to look out for when using the 42" belt, is make sure the spacer on the back side of the bracket on the 9/16 head bolt (for the tensioner) is not hitting the blower. That's what it sounds like you are experiencing. The tensioner was not maxed out on my setup, like you said yours was.
