so you have to get paid to know anything for "fact"?

At that rpm there would be no difference that you could tell. The 315's might make the engine a little lazier, but not that you would probably notice. Certainly not worth the extra cost.

What carb did you have on those 509s ?

For someone who is supposed to be so busy building things you sure have a lot of time to waste posting on the internet.
Unlike you, I do have things to do that are more important than trying once again to teach you the difference between a marine and drag engine.
where did I say the airflow was "different"?
Because you even have to ask me this question shows that you don't know anything about marine engines. (or I guess you think a 600 cfm carb is enough for a 502 marine engine). Maybe you should stick to drag racing sites.
you have a nice day posting while the rest of us that have work to do in our jobs get back to work.

Please stop trying to act like you have the slightest clue, about what i "understand" . While you have been standing at the dock dreaming of those silent thunder days, Ive done plenty of carb tuning on 900 plus hp roots blown marine engines , NA engines, and some blow thru deals making 1200 plus hp. and certainly not the guy who would be recommending a 650 carb on a marine 502. My current 468s have twin 850s on them.

I have enough hours and enough motors done to know BS builds when I see them. Just because I am not a "professional" has nothing to do with it. Just because you do it for a living, doesn't make you the expert. How many people thought Trick Marine was great???
