Sorry for the excitement but I finally finished my 75 Rogers project. I replaced a worn out 455 with a BBC and took it out to Smellsomore last weekend. Other than completely destroying a Fram oil filter (never do that again), everything worked out great. All stainless hard line water and fuel lines with a set of custom water valves. Modified 1/2" AN T fittings with cap bolts to meter the exit water flow.
