Carbs for GM 602 Motor

With the increasing popularity of classes that require a sealed “602” motor, the demand for power through bolt-on parts has kept pace. We’ve spent a lot of dyno and track time with these. We offer crate carburetors for the “602” motors built on the 80541 650 HP and the 4777 650 platform. Our carburetors are built to comply with the rules of the sanctioning bodies including IMCA, USRA, DIRT, UMP and others. We offer these in everything from base model carbs to our Ultra Lightweight version and have upgrade options in between. These carburetors are custom built per application and set up for the fuel being used.

Carbs for GM 604 Motor

We have a full line of carbuertors for the 604 crate motors available calibrated for gas, E-85 and methanol. We offer several different venturi and throttle bore options, and they are available in all options from base model to our Ultra Lightweight version with upgrade options in between.

Using the right carburetor on these motors makes all the difference. These carburetors have proven themselves in Fastrak, NeSmith, ASA, UMP and others sanctioned crate classes.

IMCA A-Mod racers, we have what you’re looking for! Everything is built to order based on the fuel that will be used, track and driver information, and the features requested.
