Holley Carb choice ?
I am currently running a 355 SB with a set of vortec heads alum intake and roller cam. What is the benefit of running a 600cfm dual feed compared to a single feed Holley?
I am currently running a Weber four barrel.
Thanks

I think that boats generally need more carb than automotive motors (they require more fuel because they work harder). I also think your 600 cfm on that motor in a car would be on the edge. For a street app...I'd rather see at least a 650 cfm...so, with my thinking, your motor, with vortec heads, an aluminum intake and a roller cam in a boat would require AT LEAST a 650 fm carb. If you could find a 700 cfm...I bet it would run better in your boat.
I maybe off in my thinking....just my opinion.

Correction EZSTRIPER
The Weber came as factory as follows:
7.4 came with 750
5.7/5.0/4.3's came with 600's.
Anyone have advice on my original question about the benefits of a dual feed compared to single?
Thanks
You all have a good summer

Here is a post from a few weeks ago.
Use the link posted to calculate the amout of CFM you need.
600 CFM is perfect for that engine unless you plan on spinning
in 6,000 + RPMS.
