RB Concept – ST28 RotoStart Engine

The new ST is a .28 big block mill using the same design as our RT line-up. The engine features an ABC 3 port liner and comes with the strong, resiliant MSC re-inforced crankcase. Also a standard feature we have included a roto-start system for ease of operation. It’s adjustable position of the starting nuts allows for the engine to be mounted in practically all chassis. You can also use a bump start if needed.
