engine question 2bbl or 4bbl carb

[Miles Offshore]

personal opinion but i would go with the 4 bbl. better fuel economy, performance maybe and that edelbrock is imo a better carb than the holley- for marine use anyway. I did the same thing as you mention on my old 351 i had in an old mako. was well worth the trade-off.

Before you put it in I may checkout any additional HP items than just a carb. I would look into a different cam as well, its easy when its out of the boat and may give you another 40 to 50 HP, a 4bbl version may have come with a different one than the 2 bbl. anyway and I bet it did, thats a heavy boat you can't get toooo much HP in it. I would even go a high performance cam instead of just a standard manufactuer.

Thanks all.I want as much power as possible,but i also want a smooth trolling speed out of it.
I'don't want to get too radical,and end up with an engine that idles like a race car.
It's primary use,other than getting me to a fishing location quickly,will be to be able to troll at 2.5 to 3.5 mph smoothly for several hours at a time.

Is a fuel injected engine worth the xtra? iam looking myself for a complete package.

But you want it to make that power at low to midrange RPM.

Think about it. You want it to make max torque at around 3000 RPM. That will keep you out of the secondaries on the 4 Brl and give you decent fuel millage. Something in a RV style camshaft.

They make cams that make the power all thru the RPM range, yes he would want one that makes it at the lower end.
