1947 American-LaFrance V12-J Marine Engine Conversion |
I bought this engine in original condition in order to build something a little different to power my 1954 Chris Craft Riviera racer project. I fabricated a 1" thick aluminum adapter that allowed me to bolt-up a Crusader bell housing (GM to Velvet Drive transmission) with a rear-mounted reverse rotation starter. I mounted a raw water pump from a 7.4L Mercruiser and made the modifications that were needed for the cooling system. Modifications included: GM 1-wire alternator Twin Carter 2GC carburetors Crusader outside ring gear flywheel Holley electric fuel pump and regulator Vintage McCulloch VS-57 supercharger Custom dump to exhaust thermostat cap/bracket |
The smaller diameter GM flywheel required the starter to be rear-mounted so I used a vintage Crusader GM 350 Velvet Drive bell housing with a reverse rotation high torque starter. |
This engine has two 12-point distributors, four sets of points, four coils and 24 spark plugs which required 112' of vintage cloth-wrapped solid core spark plug wire. |
Painted with 1956 Chevrolet Tropical Turquoise |
