After having changed my mind on my swap, I have decided to sell my allante steel rocker assemblies as I'm leaning toward the Ls4 now but these will give you another 2k than the 4500 stock redline on a 4.9. Though they have been on the forum more recently they are typically hard to find as GM stopped production on them. Looking to get $200 shipped. Paypal only. Pm me if interested. Can email pics if desired.
