Single plane on a street car??

Rani, I have a Holley Street Dominator right now on a 318. In most cases, the single plain is not what you want for a daily driver unless you have decent gears, good converter, or a stick shift car. However, the Holley SD is meant to build low end torque, thus the reason it's called a "street dominator". It actually does well on the low end..... however......
Here is the kicker: Even though the above what i wrote is true, the Holley SD only has 318 size ports as mentioned in a post above and wouldn't be my choice for a 340. The factory 340 intake would be better than the SD in your particular situation.

But that is a moot point on all but hotter street engine builds, IMO. Remember, Chrysler did it on millions of engines, but the other way around.......which is much worse. Big port intake on a small port head.......but it worked well.

A small window intake on a big port head could actually have some advantages increasing velocity on a mild to moderate engine build like what Rani is talkin about. I say since she has it, she should use it.
