352 help
I have a FE 352 in a 67 F100. It currently has a Carter AFB 625 carb on it also has a Mallory dual points dist. I'm also running Flowtech headers. A friend gave me a edelbrock 750 carb. Wanting to know does anyone know if this is to much carb for a 352.

I'm not worried about burning extra gas. I'm looking for more horsepower by the way of adding intake and bigger carb. I was just wondering if this was a waste of time.

Go look at the tailpipe now, is it sooty? Sniff it, does it smell like the choke is on?

To significantly increase the horsepower beyond a stock well-tuned engine, you need to increase the overall air flow through the engine. This involves putting on higher flow heads (with bigger valves and/or bigger ports), a longer duration cam, headers, a higher flowing intake manifold, and a higher flowing carb. You have to have higher flow through all of those parts, not just a couple of them. If you just put on headers, bigger intake, and bigger carb, without the heads and cam, you probably won't gain much and may even lose horsepower. Putting on an oversize carb is bad because you're actually slowing down the airspeed through the carb, which hurts the ability of the carb to atomize the fuel into the air. Getting the fuel/air mixture right is critical for horsepower and throttle response. Just pouring extra fuel in there will slow you down.
Unless you do the whole package, your 352 doesn't need any more carburetor than you have.
Personally, I think that the Carter AFB is about the finest high performance street carburetor made. It's completely adjustable in all ranges and can be fine tuned for any engine and car. Why on earth would you want to exchange it something else?

I have already done the whole 352 package. As I stated before it has a mild comp cam,flowtech headers, edelbrock performer intake, only thing I haven't done was install bigger airflow heads. I have had the carter rebuilt along with the edelbrock, but the intake calls for a bigger carb than what I had installed on it.
