Just a follow up on Jay's adaptor and the CHI intake. I installed both and they went on with no problems except it was 3/4" higher then my last setup which means it was 3/4" to high and was going to hit the hood. I decided to modify the air intake. The last setup I had on it was a K&N 1 1/4" drop base with a 3" air filter. I took the drop base and modified it so that it was a 2" drop base with a 3 1/2" air filter.
Here is the manifold installed.

Here is a video of one of my shake down cruises where I am first testing the higher rpm and trying to record the gauge readings. My shift light is going on at 6500 rpm. By the time my brain figures why there is a red light and that I have to shift gears, I think I am at about 6800.
