OK , I just bought a Nash flat 6 today for a future project . Everyone who has an aluminum 2 carb head reply immediately so I can compare offers .
I have an Edmunds side draft for the overhead valve sixes from the early 50's. about 5 years ago I saw the dual intake for the flatty, wish I would have got that one.
Geez, I've been rocking the stock stuff because I didn't think there were speed parts for this motor, lol. 90 hp stock, what's a head swap and an extra carb worth, 10-15 hp?
