Is there much of a difference between the C&L Upper Plenum and the Trick Flow? I know the trick Flow is 3/4 inch taller which is good for more HP.
I was thinkning of one of these with a BBK 75mm Throttle Body.
I'm personally very satisfied with my C&L. Others have had different results. But, I feel with the proper set up, anything could yield satifactory gains. Pick and choose parts that you think will mesh well together and get them.
One guy will tell ya.. "dude this thing is freakin awesome, you gotta get it", while another will tell you it sucks and product_b is better than product_a. They're all about the same in performance. With negligable differences.
