Suggestions on carburetors

I am ready to buy a carburetor for my 32 pick-up truck but I am total confused when it comes to CFM's,,

I plan on using a single 4 barrel carb,,,

The engine is a fresh 30 over 327 w/t 300 horse heads,,,hydraulic cam,,,just a simple engine,,,

I am using a 350 ******,,,HRP

 

I'd look at an edelbrock 650 for out-of-the-box drop it on and go performance. My dad swapped one onto his car awhile back and it was that easy. Never had to tweak it at all and runs better too. I've had good luck with holleys, but I'd probably go edelbrock unless it was something I wanted to tweak for better performance.

Holly has a web site and there is a selection on
" how to select the right carburetor size" which might
be of some help.

Too little is always better than too much.
The 2 most common Hot Rod mistakes are too much cam and or too much carb.
5-600 cfm should be more than enough for a mild 327.
Here is the simplest formula around for determining CFM------CIDxRPMxVE divided by 3456
(Volumetric Efficiency is typically around 75-85&#37
I'm a Holley kind a guy.
They're simple and tuneable as hell.

 

I just bought a 750 cfm Edelbrock for my 390, but it won't be a 390 forever, and i wanted to use the same carb on the next big thing that goes in it if possible. 5-600 should be fine unless you're planning on reving it to 10K or something ridiculous like that.

 

If you err on the side of large-ness, later, when you stuff the throttle you will discover a phenomena I came to call "Niagra-Falls-in-the-Manifold" And a season later, after the raw fuel has washed the oil off the cylinder bores again & again, you may begin seeing the faint blue wisps of smoke....from the tail pipes!

SBC's snap to life w/a 600/650 cfm carb.

The above results were from running a "free" Offy 2 X 4bbl manifold w/2 Carter AFBs on a 327 SBC...either one of which fed a 389" Pontiac easily.

 

My choice would be a Holley 600 and take it out of the box and bolt that ****er on and go, its really just about that easy, Edelbrok is the same but i just happen to like Holley better.

 

Yo Baby is right. 5-600 is plenty for a street-driven SBC. I'd recommend a single line Holley. It will come too fat out of the box so you'll probably find you'll need to go a couple of sizes smaller on the jets (probably 64s) especially since you're close to sea level.
