Naturally Aspirated 260hp 350:
As is evident from the graph, the Jegs/GM crate motor was designed more with economy in mind than maximum power. Rated at 260 flywheel horsepower, adding a small Quick Fuel carb, Edelbrock Performer intake and HEI distributor allowed the 350 small-block to produce peak numbers of 264 hp and 353 lb-ft of torque. The low-budget normally aspirated crate motor was equipped with a 4-bolt main block, LT1 PM rods and cast pistons (all new parts, by the way, not remanufactured).

Jegs/Vortech Supercharged 350:
As expected, adding the Vortech supercharger dramatically improved the power output. The peak numbers jumped from 264 hp and 353 lb-ft of torque to 383 hp and 431 lb-ft of torque at just over 7 psi of boost. The efficient Vortech supercharger improved the power production of the crate motor by an impressive 45 percent. Even more important is the fact that this supercharged 350 comes complete and ready to run.
