the yella terra rockers are shipped to mike from Australlia, so if it wasn't for mike, we wouldn't have them available. most of the cost of the $545 is in shipping. take out $100 for the lifters and pushrods, so your at $445 for the rockers themselves, now figure, a good set of roller rockers for a SBC could cost $400. now the price for the yella terra full rollers, isn't such a bad price at all, considering shipping costs contrey to contrey
