What's Included: This is a base dressed, fuel-injected engine. It comes with a dual-plane satin aluminum intake manifold (BPP350VINT), a Holley Sniper 2 EFI System (BPP550-510-3XX), a fuel pump block-off plate (BPP42463), a distributor (BPP350RBK), a BluePrint dipstick (BPP9420), valve covers (BPP9518), a timing cover, and an oil pan.
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. BluePrint states this engine is not for EGR. The engine package does not include a fuel pump and is configured to run in fuel-only mode, and an aftermarket intake may not fit OEM accessory brackets that use intake-mounted bosses.
