The Kaase manifold is very similar to this Morrison intake.
When Dan Jones was still posting here he mentioned that he ran the numbers of the flow characteristics of it through his program and that the results that he saw indicated that it "tended to be restrictive" (in Jones "speak"). The down drafts showing much less restriction.
The length of the runner from the intake valve to the bottom of the throttle plate was thought to be around 4.5" to give the best balance of HP vs. TQ.
IF that is factual, these cross rams neck down and are too long.
I am pretty sure that he hadn't at the time dynoed them. I would be very interesting in seeing those results if he has since?
The 48ida Webers show restriction on 289's somewhere in the 6 to 7,000rpm range with 42mm chokes. Dan's computer model suggests that 54-55mm throttle bore on a 4v Cleveland 351 is about right. Problem is, that doesn't exist and there is no cast intake exists that has runners cast thick enough to allow that kind of a bore inlargement.
The Hall Weber manifold that I have measures about a 51mm bore.
The only reason I mention that here is Kaase's description of operation tends to be contradictory to the Jone's data. Personally I couldn't confirm any of that but it is worth mentioning in my mind?
