What's Included: This is a deluxe dressed MPFI engine with the polished pulley kit. It comes with BluePrint multi-port fuel injection with a self-learning ECU and complete wiring harness, a single-plane machined aluminum intake manifold, a standard-rotation aluminum water pump (BPP67265), a 14 inch polished chrome BluePrint air cleaner, polished chrome valve covers (BPP9518), a BluePrint dipstick (BPP9420), a fuel pump block-off plate, spark plugs (BPP7938) and wires, a harmonic balancer, a distributor, a timing cover, an oil pump, and an oil pan, and a polished front accessory drive (BPP350FDACPS4) consisting of a reverse-rotation short water pump, a Type II power steering pump with remote reservoir, a 140A 1-wire alternator, and a 7B10 peanut-style A/C compressor. The BluePrint-designed ECU is fully calibrated for this engine, locked, and self-learning.
Engine Platform: Built to the GM small block (SBC) platform. The engine is sold as a 383, but a true 4.000 in bore with a 3.750 in stroke works out to about 377 CID. The aluminum heads use a .500 in raised port versus an OEM casting. The BluePrint ECU is tuned specifically for this engine and self-learns as bolt-ons are added. BluePrint states the low-profile front accessory drive does not fit all Corvettes, and buyers should confirm fitment before ordering.
