I'm going to use my car to take the kids to Sonics, etc...As you mentioned you were going to use the car to get bagels on Sunday morning I think you're wise to keep it stock or real close to it. I recently put a Keith Long tranny in my 340 Duster which has 3.23 gears, 727, TQ, stock manifolds, one up from stock purpleshaft cam. Keith recommended no more than a 2500 and shipped a custom one from PATC. I have the original stock converter, which would work for you, if you're interested...probably better off getting a new one, but if you're on a tight budget...could have it checked out to make sure it's ok. I hope to get the car on the road soon to check out the combo...never heard of anyone not happy with Keith's recommendations...good luck! Mark
