Available now from Summit Racing are Mast Motorsports GM LS crate engines, which are hand-built using the best parts available, then dyno tested on Mast’s own engine dyno to validate the performance. An example is the Mast Black Label 650 Street and Track LS7.

Producing some 650bhp (505bhp is stock figure for an LS7) it packs a 570 lb/ft of torque punch and the block is a machined and blueprinted aluminium LS7 item with Mahle forged pistons, Callies H-beam connecting rods and forged crankshaft along with Black Label 285cc cylinder heads and Mast ECU.

Summit Racing offers Mast Motorsports crate engines in over 90 configurations – EFI, carbureted, supercharged, you name it. Long blocks are also available. With so many to choose from, we do recommend consulting with a friendly Summit salesperson to ensure you get the right engine for your project.
