Why is Oval better then Square port?

Port volume, not shape. The 270cc runner is better suited to your cubic inch and rpm range.Blade wrote:DOTracer wrote:from the basic info provided the RaceRite oval would be a great choice.

I would agree with that!DOTracer wrote:Port volume, not shape. The 270cc runner is better suited to your cubic inch and rpm range.Blade wrote:DOTracer wrote:from the basic info provided the RaceRite oval would be a great choice.

Yup, you need a plexiglass plate with a hole you put over the intake flange sealed with lithium grease. Use a buret filled with colored rubbing alcohol and read how many CC's were poured.Blade wrote:So you also wanna match the Cam to the Heads?
Also how do you find out the cc? Is there a tool to measure?
And I'm certainly no expert either, but it also has to do with rpm, cam duration and linear air velocity. Please note that I speak from the perspective of big block builds, but the same rules apply across the board.Bruce69Camaro wrote:Actually with that size motor, which is not too far off from mine, my builder recommended using the oval port, Edelbrock alum heads with the 2.19/ 1.72 valves. I think (?) the CC was around 290/300.
Might want to think about those, but I'm no head expert, maybe someone can back me up on this?
