Default moroso vacum pump & msd crank trigger

what is the purpose of having a vacum pump as well where does
a crank trigger work with the timing, building a 496EFI and notice
some of the strong motors use the pump and a trigger, should
i consider using these and would they benefit, thanks for helping

A vacuum pump helps greatly with crankcase ventilation to help reduce windage. They do add 15-30 hp according to some dyno figures I have read about. Less windage, more horsepower. A crank trigger all around keeps your timing where it should be. With a proper crank trigger set up I have never seen our timing vary at all. A crank trigger will not increase horsepower, but is a reliable piece to ensure your timing stays where it should be.

Default lets vacum

thanks sst521mechanic
i have seen john cunningham build some strong sbc and each had
a vacum pump, i think i will add it to the 496 to keep the
motor at its best with a trigger thank again
