D64 / A dual quad Edelbrock (and other intakes)
I'll list up some interesting measurements I took.
(OH!, The intake sat on top of the above pictured 360 well enuff. Intake bolt angle is the issue.)
Port window diamentions (Ruffly preety close);
Pictured in order below;
D64 - 1X2-1/4
TorkerII & RPM - 1X2-3/16
Holley strip Dominator & LD340 - 101/8 X 2-1/4 (And you wondered why those two intakes kick ***! Theres a good start!)
Can anybody measure up a Offy Port-o-sonic?
