CARB HELP for the new guy
Well howdy gentleman...have been checking out these forums for a while now as a guest so, now im searching for a few answers so i signed up...
To get down to bussiness i recently bought a winter project, 77 f100, and need to replace the huge double pumper summit thing that someone slapped on my intake... here are some specs on my 351, any ideas would be much appreciated... looking for performance but i do drive her daily..whens shes not tore apart anyway...
351 bored .30 over
vodoo cam .473 valve lift intake at 289 degrees .497 vavle lift on exaust at 300 degrees rocker ratio 1.6:1
heads are shaved .20 with the intakes at 1.940 and exaust at 1.600
combustion chambers at 59.5
cheapo high rise summit intake man.
and the carb i need to delete in a 800 something double pumper

My own personal preference are Holley carburetors.
On a 351 I wouldn't go any larger than around a 600cfm 4bbl with vacuum secondaries. Your preference on whether it's an automatic or manual choke and if it's an auto trans., go with one that has the Ford kickdown linkage.

I agree Mike. Love the Holley carbs cause they are a snap to rebuild and easy to tune. Using their carb selector, they recommended a 650 w/electric choke for my mildly built 460. She runs great with it.

I can never remember if your UserID starts with an "o" or a "0"... hence, .. +Zeros.. or would you like "Oh"s? Then it'd be "Mike OhOhOhOhOhOh".... sounds painful!

actually it's mike oh, zero, oh, zero, oh, zero. I can thank AOL for that one. Years ago, when AOL was about the only game in town (remember dial up?), I joined up. The screen name I chose was already taken and they assigned me that one. Why bother changing it? It's only my AOL screen name and e-mail no big deal.....Flash forward 20 years, NOW that %$#!#$ name is tied to just about everything I do 
.Don't feel bad HIO, that name throws EVERYBODY.

sounds like good advice. i kinda like my summit 750 double pumper, but it was too much for what i needed and i think id try the smaller one's still, theyre really easy to work with being holley-based all the jets and parts transfer

I prefer holley to edelbrock, Holley builds one HE11 of a product. Mine have always run awesome, even my brother took one I had because it ran so well then I just made another one that ran awesome too. Good luck.
