Experience Counts

Marty Bernard - '66 Chevy Biscayne w/ Hot Rod Carbs - Rochester 4GC NHRA / IHRA Record Holder - Best Appearing & Best Engineered Card Award Winner

Our business AUTOMOTION Rochester Carburetor Service, was started in 1983 with the sole intent and purpose of providing ‘Custom Built’ Rochester 4-Jet (4GC) and Q-Jet carburetors to the o.e.m. muscle car restoration market and to nhra / ihra stock / super stock drag racers. Both of these market segments require a knowledge of carburetor function, vehicle air & fuel requirements, and a sharp eye for detail. You can say that we cut our teeth on these two carb models.

* We’ve had a number of customers set nhra / ihra national records with our race prep’d carbs

The Heritage Continues with Our ‘Custom’ Hot Rod Carbs Tri-Power Systems

 Larry Fulton - Street Rodder Magazine July 1998In 1994 ‘we were discovered’ by Smitty Smith @ Edelbrock and it was Smitty who originally encouraged us to start building these Rochester based Multi-Carb Street Rod / Hot Rod Systems, using their reintroduced #5419 SBC 3-Deuce Intake Manifold. This is when the Authentic Custom Hot Rod Carbs Tri-Power brand was born!

We continue this Hot Rod Carbs focus today by now offering 35+ different applications of Custom Built – Custom Finished – Engine and Application Specific multiple carburetor systems. ALL are intended for the Street and ALL are based on the versatile GM Rochester 2-Jet carburetor.

Our Systems have been used on everything from Daily Drivers and Hot Rods, to TV Feature Cars ( Horsepower TV ’32 Coupe ) and Full-On Show Cars, including the following; The 2008 Good Guys – Street Rod Of The Year; The 2010 Street Rodder Magazine – Street Rod Of The Year; The 2015 Hot Rod Magazine – Street Rod Of The Year; The 2015 Street Rodder Magazine – Street Rod Of The Year; The 2017 Detroit Auto-Rama Riddler Award Runner-Up; The 2019 Detroit Auto-Rama Riddler Award Runner-Up; The 2020 Good Guys – Street Rod Of The Year.
