intake swap

[vratman]

I have a dual plane intake that has 2000 to 6500 rpm, the one I want to replace it with is a weiand intake 2700 to 7200 rpm cam is 1500 to 6500 rpm will this work with out problems?

Less low-end response.

Which intakes do you have? what engine, cam,compression,heads,carb,gear,converter,etc,etc...................

The advertised intake manifold & cam RPM ranges are more like general guide lines. They work best within these ranges. Cam rpm ranges are less flexable but vary the most due to bore and stroke combinations. Stock or otherwise. Intake manifolds can be pushed in ether direction of there list RPM range.

Paying attention to dunk testings of various bore and stroke combinations can help reveal how a camshaft can act. The bigger the engine in bore tends to allow more top RPM and a longer stroke shortens the RPM of any given camshaft. The intake used can shorten the hand or lengthen it.

This is a "In general" working. However, variables in every part of an engine build will change everything if not just a wee little bit to a large amount.

Of all the variables, things as simple as ignition can count. Carb, exhaust track, compression, it all adds up.

Name your parts and provide specs of the cam.
