Double Pumper has to do with a Carbureator(SP?)

Two bolt main and four bolt mains, errrrr.....I cant think of the CORRECT term

A six pack is a carb setup, it uses an intake manifold that has space for 3 2 barrel carbs...You put the 3 2 barrels on, and its called a "six pack".....Ive also heard it called a six barrel carb

Mallory is just an aftermarket ignition company

Hope this helps

Default lol... Can't think of it??

Two bolt or four bolt mains refer to the number of bolts holding the crankshaft in place. They bolt onto the main caps and hold the crank snug. We have six bolt mains. Three on each side. Mallory is also known as MSD. Pretty close on the carbs. Three deuces is three two barrel carbs. A four barrel carb has four holes into which air and fuel mix. A two barrel has two barrels. The reason for three deuces is fuel economy when driving regular, but plenty of gas when you floor it.

two bolt, and four bolt mains is relating to the main caps that hold your crank in your motor in place. the number of bolts per crank is what gives the number.

6.0 blocks have 6 bolt mains. 4 on the tops of the caps and one on each side of the caps

6 pack is like what was stated....

an intake set up when using three pairs of 2 barrel Carbs

Mallory is an ignition and spark company

Double pumper is a term they use for a series of carbs holley had... the famous Double Pumpers

Double pumper is a 4-barrel carb with mechanical
secondaries; a vacuum-secondary carb does not
need the second accelerator pump. "Double
pumper" is easier to say than "mechanical
secondaries" and people who wear camouflage
trucker hats will understand you better.
