Description

The All-New Stromberg BIG97 Tri-Power – OE Finish.

On the outside of the Stromberg BIG97 Tri-Power – OE Finish, it’s Genuine 97 all the way. But on the inside, we’re talking the ultimate 750cfm hot rod Tri-Power, with new improved fuel circuits, ported distributor vacuum and a whole lot more. Add our progressive linkage and classic 3-into-1 fuel lines and you’re looking at old school carburetion with next level performance and drivability.

The pre-packed Tri-Power comes at special pricing compared with buying separate carbs. Add our Small Block Chevy linkage and fuel line and you can save even more!

55% more airflow
BIG97s make 55% more airflow than regular 97s – 750cfm for the Tri-Power, making it the perfect bolt-on for your small block Chevy or Ford. Cruise economically on the center Primary, then punch in the Secondaries when you step on the gas.

New power valve circuits improve fuel conditioning
Feeding top end enrichment directly into the emulsion tubes, the BIG97 Primary significantly improves fuel conditioning for more top end HP on less fuel.

New ‘early plenum effect’ boosts top end power
All three carbs allowing all cylinders to draw from both barrels giving you dual-plane drivability with a single-plane style top end horsepower.

Ported distributor vacuum
Switch in the brass plug (supplied) and connect your distributor to improve combustion efficiency in cruising mode. You’ll run smoother and cooler, with more torque and better fuel mileage.

BIG S-jet twin-ball inlet valve
BIG97s accepts big diameter 5/16in hard line (regular 97s take only 1/4in line). BIG style Ford nut compression firings are available, and all our regular Stromberg fuel fittings – hose ends and banjos – all fit.

All Genuine 97!
Everything that makes the Genuine Stromberg 97 so popular is built into the all-new BIG97 Tri-Power. From the cast iron base to the reinforced air horn casting and everything in between. Note: As with regular new 97s, original hand throttle parts are not included.

Runs out of the box
BIG97s come ready to run, with a wide range of jets and power valves available for special tuning to suit your individual application. Every BIG97 comes with full installation instructions and you can find more help on our Tech Center.

Chevy linkage 
Our 9246PRO progressive linkage combines clean, traditional looks with maximum leverage. It comes pre-assembled and installs in just two simple steps, without the need for extended throttle shafts. Every kit comes with two ‘Snapback’ throttle return springs, which wrap around the end of the throttle shaft and virtually disappear from view. The swivels are positively fixed by a small e-clip, and the black set-screws have knurled ends for a strong fix.

NOTE: These carburetors are not designed to meet any emission requirements for 1968 and later applications. Therefore, they should be used only for competition/off road vehicles or vehicles not required to comply with late model exhaust emission standards.
