single vs. dual tunnel ram

Does anyone know if there is a significant drop in HP running a single carb tunnel ram vs a dual carb ram.Specifically I'm looking at the Weind Hi-ram for a sbc.It's offered with two tops , single or dual.My hope is I could run the single carb base and enjoy the look and HP of a tunnel ram without the tuning headaches I hear about so often.

as long as your carb cfm properly matches the cfm of what the engine needs, a single carb is perfect

people seam to think that taking a stock 1984 camaro w/ a factory 350, and adding a tunnel ram w/ dual 750 cfm double pumpers someonhow makes huge hp gains ... that that im accusing you of that in any way

run the right size carb, and run an intake designed for the rpm your gonna see the most ..

think of it this way ... your out on vacation and you go snorkeling

you have 3 size options for snorkles

"normal" diameter that everyone uses
"tiny" .... its 1/2 the diameter it should be
and "monster" ... its a 10" diameter piece of tubing

sure youll be able to inhale enough cfm's thru the monster one if you use it ... but its not like the monster size is gonna make it any easier for you to swim better

Running a single carb on a tunnel ram causes severe distribution problems. You are better off running dual carbs with a tunnel ram.

Really, you are best off running a single carb on a lower rise intake.

two small carbs would work better than one large. IMO, but I run an enderle bird catcher so I guess I wouldn't be the best to advise on this. I would think the single would have some signal problems due to where it is mounted.
