[RICK LAKE]

bermblaster41 Berm The one dyno sheet is a dyno issue but both have the same drop of power from 2,700 to 3,800 rpms in HP. I would like to see the A/F ratios during this pull. Something is something really wrong with this motor. It also looks like valve float at 5,800 rpms. There is not enough motor for this camshaft, size or compression. It's a real disappointment that some one let this motor out of a dyno without looking into fixing it. The 104LSA may also have alot to do with this power band issue. Maybe setup of the camshaft to a 108LSA may have help smooth out the power band. If that is valve float at 5,800 rpms this explains the lifter failures. Banging out the lifters on the camshaft, or free fall to base. As Brent did say this motor needs more valve spring pressure or a change in camshaft profile. You might want to look for another engine guy who can put the right parts togeather and still give you a loping idle you want to hear. Rick L. Ps any chance you have a read out sheet on the pulls?? Look at the Vacuum , A/F, and Gas usage. Something is way out of wack.
