Intake manifold choice

Another option would be a CH4B. You can still find them on Evilbay and classifieds. They tested well against all other 2planes coming up just shy of the RPM for peak and avg numbers with a lower profile.

DP4B would be the low deck version....and yes,it's a good piece. I did notice a seat-of-the-pants improvement when I replaced mine with the RPM. JMHO
