They feature a new one-piece rear main BluePrint engine block with 4-bolt mains. Inside the block is a cast crankshaft and connecting rod rotating assembly, with 9.1:1 compression hypereutectic pistons. The full roller camshaft provides 0.481 intake/0.480 exhaust lift with 187 intake/193 exhaust duration at .050 with a 97 degree lobe separation. The engines also include a new oil pan, a set of valve covers, and a timing cover to finish them off. We purchased the last of these new-in-the-box engines from Blueprint. This means we cannot extend a warranty from the manufacturer; however, we do offer our standard 90-day handshake guarantee. This is a last chance opportunity, once they're gone we won't be able to order more--so grab one while you can!
