Just happened to see this thread. One of our Inliners, Bob Palmini, from Calif., now living in San antonio, Tx. Made and drag raced a set up like this in the early 50's. He said it would run within a tenth of a second of a 12-port. He left the stock carb., started it on that and had a progressive linkage to kick in the top three. He's an interesting guy. Raced 6-cyl. cracker box boats against the flatheads, Ran the Carrera Pan-America in 54', had a dyno facility in So. Cal. in early 50's. Mickey Thompson built a few engines there. He'll be giving a talk at the 2010 National convention in June.
