Trying To Build A Low 10 Sec. Ride

[Mustang_289]

This is encouraging, we really want the AFR185s as my son did the research and their kick butt heads. We're not ready for a stronger bottom end at this time money wise, we're just trying to step up performance on the top end with stock bottom.

My son picked out the X303 cam, Typhoon Intake, and AFR185s. Got the Xcam and Typhoon intake installed, after we converted to mass air. Motor loses power in the 4K rpm range with the radical cam installed. We believe it's the stock heads that are causing the problem with lose of power. Maybe a floating valve with so much lift on stock heads.

need to fix this problem, didn't want to buy AFR165s and then buy the 185s when we're ready for the new motor. After reading your post, sounds like we can chance going with the 185s on a stock bottom end?
