This intake fits an open class carburetor to a big valve cylinder head. We highly recommend our X380-6 Intimidator Carburetor. Not only is it the most winningest carburetor for open class engines using cast or billet heads, but it's also the only 380 size carburetor with a fuel circuit designed for the OHV engine. The Tillotson HL-380A, B are designed for open flathead engines. This makes them finicky to tune, and they do not make the power of the Intimidator 380.
Designed and CNC machined to match each unique intake port shape precisely at the block or cylinder head. Entrance (May vary on head type and model)The resulting action is no turbulence causing misalignment and much better control of the laminar flow in the entire intake tract. By using the Tillotson carburetor, we can create the best angle through the port. The pulse hole is precisely located for increase pumping action at high RPM. All installation hardware included.
If you are looking at the intake length as a wort length tuning for the engine, you need to know. A few things The Tillotson carburetor, being a diaphragm pump carburetor, needs a good vacuum or pulse signal from the intake. If you make your intake too long, then you lose signal to the carburetor and potentially hinder its tuning and performance. Tuning your port runner length is more of an exact science than many realize, and simply adding more length doesn't always net the gains you want; where you want. Your carburetor, head ports, and cam timing, as well as where you want your engine to gain, are all part of the science of port tuning. Unless you have the equipment, time, and money, it's difficult to test the theory, and your gains may be minimal.
