The 4412 carburetor is originally designed for use in a dump truck and construction type commercial vehicles. So making improvements on the design is an easy one.
Correcting the fuel curve and maximizing air flow with mods that straighten the air to improve flow YET WILL STILL pass GO-No-GO gauges is what we are all about here at PRO SYSTEMS.
