Product Description
Vacuum Control 70–71 SBM w/ Dual Points
New reproduction vacuum advance unit for 1970–71 340 Small Block engines with the cast iron dual point distributor.
Fits all 1970 and 1971 340s with factory dual point distributors, including T/A Challengers and AAR Cudas equipped with the 6-pack (6-pak / 6bbl / 6 barrel) carburetor setups.
It’s hard enough to find an original distributor for your car – but even harder to get a working vacuum advance unit.
Many originals fail due to leaking internal rubber diaphragms.
Treat your car to a brand-new, shiny vacuum advance that not only looks right, but actually works the way it should!
