An intake upgrade is not out of the question now that I have throttle body injection, which won't be affected by the installed angle of the engine. The CC 427 intake has the carb mounting flange angled to compensate for the installed angle of the engine to keep the carb more level. Automotive intakes do not have that feature. I am not sure how much having such an angle to the carb will influence performance. I was originally going with the carbs Glenn will be using and was concerned with going to lean with secondaries wide open if I were to use an automotive intake. I opted for the Holley 950-52 system to gain flexibility for tuning fuel and timing with O2 and knock sensor feedback. I want to see what fuel efficiency I can squeeze out of these big dogs too. I may be over analyzing the carb and aftermarket automotive Intake combination in the 38 Commander application. Any thoughts?
I am keeping the original heads and the intake ports are well matched to the original intake runners. At 4,000 RPM and below, I am not sure how much an aftermarket intake would actually improve the performance compared to the original. I did block the exhaust crossover ports which will keep the manifold cooler, another benfit generally associated with an aluminum intake. Maybe we will see. I can get them dialed in with the original manifolds and the change to the 390s. It's only time and money. I like playing around like that as much as I do sitting in the cockpit drinking a cold one staring out at the water. By the way, I am sitting on the gas dock at Green Turtle Bay enjoying the day before the boat races. I wish I had the Commander here too.
