Andrew, it really depends on your build and future plans. Unfortunately, there isn't a clear-cut "these are the best" option, and since the RedHot works well in both N/A and boosted applications, that can change the recommendation as well.

The LS7 lifters are a good, proven option, but we completely understand wanting something a little more robust—especially if you plan on pushing the build further.

In that case, I definitely wouldn't overlook the GM Racing lifters aka Caddy Racing Lifters. GM states these lifters have been **tested to 8,000 RPM**, so they're more than capable of handling some serious abuse. Of course, we're NOT recommending spinning the RedHot cam to 8,000 RPM—that figure simply speaks to the capability of the lifters themselves.

They work great in both N/A and boosted applications and would be my recommendation for a great balance of performance, reliability, and affordability.
