Good Luck
Good luck trying to get roller lifters, there was ONLY one or two companies building roller rockers and one of them folded, which poses a problem if there was only one to begin with. Crane and Comp etc just repackage these lifters in their own box.
I was very lucky that the roller lifters(have the stabilizing bar connecting two lifters together) for my Cleveland were only on back order for two months. I have also heard that roller lifters for small block chevys(generally the the cheapest engines to build) are selling for up to $1000 a set, I spent $400 for the Cleveland set, and every thing costs more for the Cleveland.
If anyone wants to make grips and grips of cash start making roller lifters, beacuse the market is crazy for them.
