While I’ve still got a fair number of NOS Small Base Rochester 2-Jet carbs to build into 3-Deuce and 4-Deuce Systems, I’ve recently gone full circle back to my beginnings of 50+ years, Restoring & Building Chevrolet style Rochester 4GCs for Classic Cars, and NHRA Stock & Super Stock racers. This will always be my favorite model of carburetor. ** I will not sell anyone a POS from the bottom of a lake bed. No Rust. No Corroded Base Plates. NO LOOSE THROTTLE SHAFTS! NO ILLEGAL BS LIKE I SEE THE COMPETION IS DOING!! Your Cores or Mine. ** I’m taking orders for these builds. I have the parts, pieces and experience like no others.

I was just reminded that this is our 25th Year of being associated with and recommended by Edelbrock ( 06/94 to 06/19 ). The relationships that we’ve made with people there, or that have come from their recommendations, will always be some of our most cherished. Thank You to everyone that has helped promote us, and support us through all of these years. 

NHRA “World Champion” Sammy Pizzolato, just sent us a few photos and some comments after using a set of 3 of our Big Block CORVETTE Tri-Power Carburetor Insulator Packages on his own 1969 Corvette street car.

“These carb insulators are a must for every Big Block TriPower Corvette owner”… “It’s so nice now, to be able to shut the engine off, and not have to worry about carburetor percolation and gas flooding over into the engine”… “These really do work! Thank You for manufacturing such a great product.”

Thank You Sammy for the awesome endorsement, and because of the special material that these are made out of, we know you will appreciate them for a long time to come.

* Set of 3 – 1/2″ Thick – “Bonded Pair” Heat Insulating Spacers & Shields (there is no gasket between spacer & shield); with longer studs, nuts, washers and plenty of gaskets are now priced @ $207.oo + usps priority mail (please note, that the logo will only appear on the center carb bowl shield, and not all 3 insulators as shown in the photos here, that were for display only (the one logo is very discrete, so much so that most people never even see that it’s there).

The testing is done and we’ve proven our point that the printed CFM Ratings supplied by the Rochester Products Division (RPD) of GM has been incorrectly documented from the very beginning… Realize, that compared to the equipment that is available today, RPD was using antiquated equipment and more theory than actuality in determining their flow numbers… And unlike Holley & Carter who used cfm ratings as part of their performance marketing campaigns, GM (RPD) actually would have preferred not using any CFM Ratings with their carburetors at all… The Small Base Rochester 2 Barrel Carburetor CFM ratings that we have proven, comes from the differences in the diameter of 5 different models that range from 1″ up to 1.250″…  My Thanks go to Nick Smithberg @ Smithberg Racing for having the skill, the equipment, and the want to do this project with us… Nick tested all of the 5 sizes; using multiple pressure drops and flows; and all testing was done with and without the air horn bell for comparison.

340″ MOPAR 6-Pak Intake and Carbs – AUTOMOTION / Hot Rod Carbs
Holley 2300 Carburetor Heat Insulating Spacers & Shields

Hot Rod Magazine – ‘Parts & Stuff’ – August 2014

Carburetor Spacers Heat Insulating… Despite the advancements in late model efi, the carburetor still rules when it comes to “True” Hot Rods and O.E.M. Muscle Cars.

AUTOMOTION / Hot Rod Carbs has released it’s own line of ‘Premium’ carburetor heat insulating spacers and spacer shields that help minimize the ill effects of the gasoline blends that we all have to contend with today.

Popular 2-bbl. models are available now. 1 bbl & 4 bbl models coming soon.

Each insulator is only 1/4″ thick for applications where hood clearance maybe an issue (some insulation is better than none!)… If you are sure that height is not an issue or concern a “Configured Pair” of a little more than 1/2″ thick is the recommended insulation for each carburetor.
