Exactly what I'd hoped to find, thanks very much. I've found conventional downdraft manifolds and a Rochester B (both from a 235) that should work well enough. Bet there'd be room for the updraft arrangement in a 3100 if someone wanted to go that route. Doubt the exhaust pipe angle would match the updraft exhaust though.
