new 350 chevy startup!!!!!!

hi everyone i am currently turning over my brand new 350 380HP motor that i built thats in my nova. it goes from the fuel cell to a new fuel filter (summit racing) to the front of the car the a HP Holly fuel pump up through a very small filter to the 2 feed lines of the Holly 650 double pumper.

how much cranking time should it take to get the gas from the fuel cell to the motor (carburator) through -6AN steel braided lines?

thank you in advance!!!

Gravity and the weight of the fuel in the tank should bring the fuel to the pump on the engine. You could break a fitting at the inlet of the pump and see if there's fuel there. From there the pump should supply the carb with fuel fairly quickly. You could pour some fuel down the bowl vents to get it started.

The pickup for the fuel should still be down near the bottom of the tank. 22 gallons of fuel should be enough weight to push the fuel through the line.

Get a plastic squeeze bottle(catsup or mustard bottle) and fil the carb through the vent tubes, this will motor started right away and get tehe fuel to the pump also. You want to do everything you can to get the engine to fire on the first couple times it turns, fuel in the carb, timing as close as possible etc.

you could just drop a few teaspoons worth of gas down the carb to get it to fire a bit, then the pump should get going enough to fill the carb. Or even better put some gas in the carb bowl!

Exactly right. Everything needs to be ready to go. Minimal grinding on the starter and zero idling time for 20 minutes. The lobes and lifter crowns are lubed by splash off the crank. If the crank isn't turning fast enough to provide splash lube, the lifter crowns will go south on you.

This is assuming a flat tappet cam. If you're using roller lifters, just fire the motor and drive it. No break-in required.
