The relationships that we’ve made with people there, or that have come from their recommendations, will always be some of our most cherished.

1967, 1968, 1969 Big Block Corvette Tri-Power Carburetor Heat Insulators

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).

Rochester 2 Barrel Carburetor CFM Ratings

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.2GC - 1 3:32" VENTURI

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.

Edelbrock X3 – Early Chrysler HEMI


6-Deuce HEMI – Edelbrock-X3

Edelbrock X3 – 6-Deuce Early Chrysler HEMI

Here’s my rendition of a properly built and assembled 6-Deuce Rochester Carburetor System, using a 55 Year Old Edelbrock X3 Cross-Ram Intake that I restored in-house.

Everything runs and idles just on the center two carbs.  The corner four are functioning secondary-dumpers that only flow air & fuel once you start to pull them open… When that happens, HOLD’N ON!!… None of this build was as easy as it looks… But it was very, very satisfying in the end.

We’ve got an 6-Deuce Edelbrock X4 – for Big Block Chevy that is available as well… Give us a call to place your order for that rare piece before it’s gone as well.

Thank You

HorsePower TV 1932 Ford

Some 13+ years ago we did a Complete SB Chevy 3-Deuce build for Chuck Hanson and the guys at HorsePower Tv for this 1932 Ford 3-Window Coupe build they were doing on series.

After loosing track of the completed car during all of this time, ‘out of the blue’ the owner of the car calls us the other day, to tell us how well it is still running after all of this time and 30K+ miles later, and asks If he “should maybe consider giving the carbs some sort of an update?”…

So we sent him some new accel pumps and a few gaskets and told him don’t touch anything else…
Now get back out there and continue to enjoy it.
