Idle to 1500RPM

[Ronno6]

Dual plane intake manifold choices tend to be divided into 2 camps:

Idle to 5500RPM, lower HP
1500 to 6500RPM. higher HP
In the testing I have seen, RPM for max HP is not stated.

Maybe this test is outdated??

I really don't think my motor will see 6500rpm.....

In 4 speed applications, how important is that first 1500RPMs ??

With 2.52 first gear and 3.73 diff, 1500RPM translates to just shy of 15mph....

I put an Edelbrock Performer RPM (1,500-6,500rpm) on my 454 build and didn't look back. any kind of cam that will make power is generally going to start in the 1,200-1,800 rpm range, so if you're doing any kind of mods to your engine I would recommend going just a little bit bigger. so the 1500+ power band Intake would be my first choice/recommendation. I'd be willing to bet you wouldn't even notice the "curve" difference between the two intakes by any seat of the pants driving.

In our dreams for sure... but usually conservative is better.
