BluePrint BP350CTFK 350 Cruiser Crate Engine, Dlx W/ Pulleys, EFI

This top-dress EFI cruiser 350, putting out 341 hp with 371 lb-ft on tap, adds a front accessory drive with black pulleys: an alternator, a power steering pump, an A/C compressor, and a water pump, all driven off one compact serpentine-style unit at the front of the engine.

One fitment note

Corvette owners should look elsewhere: BluePrint's fitment notes rule out that chassis for this pulley-and-bracket setup. An aluminum intake, HEI distributor, harmonic balancer, spark plug wires, and an air cleaner all ship installed alongside the EFI system on this tier.

Built for the street, not the strip

This tune keeps idle vacuum high rather than chasing peak rpm, so a stock converter and stock gearing carry on unchanged, and 87 octane fuel covers it. Bore and stroke measure 4.000 and 3.480 inches on the new, USA-machined cast iron block, with 5.700-inch forged rods and 9.2:1 compression, with 30 months or 50,000 miles of coverage behind it.

Q: Will the pulley kit fit a Corvette? No; BluePrint's fitment notes specifically exclude that chassis for this accessory-drive setup.

Between the EFI system and the accessory drive, this is the least amount of separate shopping left in BluePrint's cruiser lineup, which suits a builder who wants to drop the crate in and move straight to wiring, pulleys, and tuning.
