New Engine "Builders Guide" update.

[Smokedtires]

With your Burtz cam and head, what kind of RPMs is a Model A with the new Burtz engine looking at realistically in normal day to day driving/touring? Is there a point where the air flow limitations defeat the need to turn higher RPM's?

The updated builders guide is great BTW. The continuous improvements for the community is much appreciated.

A stock carburetor can't support much above 3000 RPM's and the stock valve springs won't follow the camshaft around 3800 RPM. With speed parts, Fred Roberts in Australis routinely turns 5300 RPM.
