Re: Can You Bolt on a SRT8 manifold onto a 2005 5.7 hemi? grand cher limited?
They do have adapters, and a few have done it. You're probably going to loose a little power though. It's like putting too big a carburetor on a car. Looks nice, but won't flow properly. If you're going to do headwork, headers/exhaust and a cam, then it might be different. Also, I believe you have to use the 6.1 fuel rails too. And, the 6.1 uses bigger (higher flow) injectors, which you don't need on a 5.7.
