guess holley doesn't know either.. you should go pitch your thoughts to them.. at it save them a ton of dough..
That would actually lose holley a ton of money... And that's where professional carb shops come into play, fixing holley's short comings.

That old wives tale comes from people who can't build and tune carbs.



thats just silly.. if that had any truth to it, all the carb based engines at engine masters would have the biggest honk'n dominator on top..
they don't

The tunnel ram works very well on boats and will make the most power on your motor.
But do not make the mistake of choking it with tiny carbs. Use two 650's or two 750's
on it. Two 750 edelbrocks would be cool.
A cross ram would fit under the hood!

You can up grade your 650 holley to a 750HP using the Holley or Proform
HP 750 carb body kit. It works very well and is well worth it.
Fraction of the cost of a new carb. All the gain.

F-BIRD'88 For a single 4 barrel hi performaance carb on a hi perf 350 the 750cfm holley is the best choice
99% of the time. It is every bit as responsive as a 650 if not more and aways makes more power
and torque.

If you want to actually make your boat go faster get a tunnel ram and two 650's or it.
The edelbrock street tunnel ram is a good choice. Now you will gain some MPH on the water.

This chart illustrates the power gain from a single 4bbl to a tunnel ram w 2 650's.
This 355sbc is similar to yours
http://image.hotrod.com/f/techarticl...il_chart_z.jpg

while the power test starts at 4500rpm the tunnel ram will out power any single 4 bbl manifold typically from as low as 2500-2800 rpm. You will have more mid range power.

Im running 355, World Heads, solid lifter cam and wet exhaust on my 16 foot Jersey Skiff. We can turn 7000 no problem, and the mid range creates awesome acceleration. I was thinking of going to bigger carb but would hate to lose the midrange.
