holley

I seen the Holley ultra low rams are like half off right now and naturally it got me thinking, How do these manifolds and the cobra jet act at only part throttle and cruising around, is there a loss in low end torque or are there just gains everywhere, beside cost and installation are there any...

Anyone here heard about the new Holley Hi-Ram IM? Word is spreading around of it supposedly being as good as the Cobra Jets. Curious to read your thoughts about it. Slide #1 Run 1 (Ported Holley) and Run 2 (Ported CJ) Slide #2 Run 1 (Unported Holley) and Run 2 (Unported CJ)
