how do you adjust the float level on a 650 holly single pumper
The holley has more cfm`s cubic feet per minute than a regular carb.and it also puts double the fuel into the intake faster than a regular carb.
It will work with an adapter you can get from summit or other parts stores.It would take the same adapter as a holley to a quadrajet since its a replacement for the quadrajet on gm cars.
There is only one fuel inlet. If you have a double pumper Holley then the one will branch off to two.
a double pumper is a 4 barrel carb. commonly made by holley. they were called this because they have two accelerator pumps. one on each float bowl on either end of the carb. most carbs do not have this feature, they usually only have one accelerator pump.
Rebuilding it with rebuild kit and new floats.
that was supposed to be 11:1 compression
Usually the best jet sizes for a Holley carb are the ones that came in it from the factory. Sometimes you can improve performance slightly by stepping up or down one or two jet sizes.
well a 750 vacuum secondary will work good tuned in but really get the power out a 650 double-pumper these are holley carbs. and a msd ignition system oh yeah, play w/timing to get every thing out of the engine.
These motors came with between 200 and 220 hp. That means you will run anywhere between 14.3 to 14.9 sec. on the 1/4 depending on the weight of vehicle, the gears in the rear end and whether you hook up at the tree or not.
