holley help

i recently bought a 650dp holley from the swap meet for my 351c, and am currently rebuilding and painting it. i have fully dissasembled it and glass bead blasted the outside for painting.
Is there any tricks or tips that people may know to make them perform better than your average holley carb?
atm i am getting the faces totally flat where the metering plates bolt on as years of tightening of the bowl screws have made high spots in the corners.
and what color should i paint it?
red, to match car, or something different?

Re: holley help

Paint it the colour of the car, or matt black if you are paranoid about heat dissapation.

You can rejet it to bigger needles etc if you want more form it, but I don't know any simple tricks that don't cost money.

? That would be the more fuel part of the combustion equation. Any idea where the more air is going to come from? (you remember, air/fuel ratio?)

Re: holley help

The linkage that opens the secondaries when the primaries are Wide Open - put a small kink in it so that the secondaries only open when the primaries are fully open...not 3/4 open like they usually come standard with. Jetting shouldnt have to be played with unless your gonna drag or circuit race. Stick with the 35Hg Power valve dont go to high with that one. And by that figure, it measures when to open withthe vacuum to allow more fuel thru from your manifold. 60Hg would be way to high for street applications. If you put it ontop of a decent single plane manifold eg. Redline or Edelbrock even Weiend then that will add to the power stakes. Need more info just ask.

Re: holley help

depends on how much works been done on your 351c.like cam, heads, manifold & compression ratio. if you have DP holley, they are 6 jets richer than Vac holley. rebuild carby to it's standard specs. run it, then get it down to experience ford dyno tuner. most holleys run well out of the box, with only jets & power valve change's.

ive got another question, can u feel when the secondaries open up? not as in the power, but with your foot. Is there a lump or anything? just wondering because ive never driven a holley equiped car.
with the carbie as far as i know its still stock. ill have a look at the jet sizes, and the power valves that came the rebuild kit.

its for a 9.5-10:1 351c with maybe come racing clh 575 or similar, redline torker single plain, heads are 2v ported with 4v valves, studs, guideplates and rollers.

Re: holley help

Check the list number on the front of the butterfly choke and that will tell u what carby it is for sure..it should be 4776-1 or 4777 i think for a 650dp. There shouldnt be any 'lumps' or flatspots if the carb is working well..you should just feel a good push into the back of the seat when you put your foot down

Re: holley help

750cfm DP better than 650 for that combo. i have 351c with 10.5.1, crane 280-2 HIT, redline street torker, 2V close chamber. had 650 DP, ran ok. changed to 750 DP, big differance. both carbs were unmodified

yeah a 750 would be ideal, but ill be trying to get used to a v8 in a cortina after driving the falcon.
its a 650dp spreadbore holley,

jet sizes are:
primary-60 secondary-63 i might have these mixed up

and power valve have numbers 5 6 and 7 on it, just what came in the rebuild kit, i guess it would be stock for that carb.


also how many needles is there on the metering blocks of a dp? it came with just 1 on 1 side, is that right is is one missing?
