BluePrint BP3505CTCK 350CI Deluxe Crate Engine, Longblock, Carb

The BP3505CTCK takes BluePrint's deluxe carbureted 350 dress and bolts on a front accessory drive that bundles its own water pump, an A/C compressor, an alternator, and power steering into one unit, for the same 390 hp and 410 lb-ft of torque, with the fewest remaining parts left to source.

One fitment note

BluePrint states this front accessory drive does not fit the Corvette chassis, so confirm your application before ordering if that is your platform. For most other GM-pattern swaps, this is about as close to a complete, accessory-ready engine as the carbureted side of the lineup gets. The 600 CFM carburetor, aluminum intake, HEI distributor, spark plugs and wires, and waterneck and thermostat all carry over from the deluxe dress below it.

Inside the long block

Stroke measures 3.480 inches on a crankshaft turning forged 5.700-inch rods, inside a cast iron block bored to 4.000 inches with a one-piece rear seal. BluePrint's own heads hold 9.2:1 compression and are timed to 32 degrees at 3,500 rpm, with 30 months or 50,000 miles of BluePrint's warranty behind it.

Q: Will the accessory drive fit a Corvette? No, BluePrint states it does not fit the Corvette chassis.

This is the easiest carbureted tier to plan a swap around, since the accessory drive, induction, and ignition questions are all answered at once.
