This is our upgraded Performer Plus Sy/Ty Motor and is a real bargain. We start with a selected block, then we fully machine it with improved oiling, etc for long life and durability. We take TRW Turbo Pistons, Total seal rings, new Rods, Crane Cam, a Shot penned Crank, and balance the whole assembly. Then we port and polish the stock heads and match flow them to the intakes. Stage 1 L-35 Heads Ported and Polished, Big 2,02 Valves Intake and 1.60 Exhaust, Match Flowed, and Nitrated Crank, Eagle Rods! The whole motor is blueprinted for max power. When ordering select whether or not you’ll be sending us your block for a core (other a $400.00 dollar core charge will apply). Allow 6-8 weeks for engine completion. We will contact you upon ordering to setup shipping method (shipping will be a separate charge depending on your location). Choose from Core (sending in your engine block) or no core from the pull down menu above.
