Description:

Built for Boost on a Budget.  We start with a seasoned Gen4 GM 6.0L iron block, add ARP head and main studs, a billet Dart fully-counterweighted crankshaft, Callies Compstar connecting rods and Diamond's brand new LSX Race Series forged pistons (stand-alone rotating assembly).  Then we add a pair of CNC Ported Newen Valve Jobbed GM LS3 cylinder heads with Manley Inconel exhaust valves and K-Motion springs to create a rock solid cost-effective foundation for your next street turbo build.
