First off PLEASE get the 4bbl orientation right... hating Offy's sideways stuff. Have to use a spacer to run a 390!
How about an intake, exhaust manifold combo using exhaust heat to warm the intake whole flowing better and allowing for either a 2 9r 4 bbl?
Sorta like the stock, sorta like Langdon, sorta like Clillford all combines into a nice 2 part package. If you do it right people can upgrade from stock in stages.
