Thanks Steff...cheers mate!

72 Swinger - You are correct - but the issue is more complex than just the intake.....

What I want to do first is make sure the plenum volume is not crazy....

Ive already put a temp gun on the exhaust headers and the fuel distribution has improved big time with the divider.

Once I get the Carb to Plenum ratio sorted - I can worry about the bear in the room...which is camshaft related and not an easy fix with factory slugs..

Needless to say....Im not running a cam that's 8 degrees retarded out of choice....but that's where we're at with most "off the shelf" cams and factory slugs.

Thx for your interest.
