Now Available: Low Vac signal vacuum canister that will read as low as 5" of vacuum to fully engage the stroke of the canister vacuum timing at idle on these big Duration street motors These are now available from FBO Ignition for BB and SB Mopar V-8's.

They're also disengaged at zero stroke at 2.5 to 3" so you will never have vacuum timing at WOT.

Several months ago we decided to make the investment and solve this issue. Gas isn't getting any better so it had to be done to keep our tuning products up to date with fuel formulations.

There's no argument that a street driven engine will be far happier with a properly tuned Vacuum Canister but until now you couldn't buy one. GM knew this back in the muscle car era and produced a Vacuum can known as the B-28 Performance Canister now long obsolete. It was used on many of their best and most powerful street motors of the Muscle car era... Now this engineering is available for you Mopar Guys.

We have them for Chevy's including the HEI, Mopar cast distributors and our New Billet Mopar Distributors. Ford, Buick, Olds, AMC and just about any vacuum canister can be custom built to achieve a perfect tune-up for whatever level of performance you're tuning.

5" too low? we can set up a canister for your application at 8" or 10" if needed (allow us 2-3 weeks to get them built) stock units will in most cases activate at 10 or 12".

We are not claiming to have reinvented the wheel, we use cores (OEM American Made if possible) and rebuild these units with all new internal OEM style components, diaphragms, metal pistons (replacing the Chinese plastic ones), springs, adjusting screws (American threads instead of Chinese metric) are all replaced, then the tricky part.... resealing the two halves with a crush ring. Then they are off to plating for the gold finish and ready to ship.

We are dedicated to building innovative ignition components and tuning products and backing them up with technical knowledge to help you tune your ignition properly.

As with All of Our FBO Ignition labeled products these Are 90+% Made in America and carry our unmatched 5 YEAR Warranty.
