Just one slight correction:
222 Duration, LSA 114, Intake .450/exhaust .460 inch
https://www.jegs.com/i/Chevrolet-Per...96962/10002/-1
Super chevy magazine as well:
"Loyal readers will remember that the low-compression L82 was equipped with 882 heads, L46 hydraulic cam (0.450/0.460 lift, 222 duration) and an induction system consisting of a cast-iron intake and Q-Jet carb. The Q-Jet was actually less of a hindrance than you might suspect as the 750 cfm rating was more than adequate for the needs of the 250hp L82. In stock trim on our dyno, the 9.0:1 L82 produced 313 flywheel (gross) horsepower at 5,500 rpm and 355 lb-ft of torque at 3,800 rpm. The engine produced adequate torque relative to the horsepower rating, but it wasn't exactly what you'd describe as earth-shattering."
Great example of why you need to be aware of Gross Flywheel HP versus Net HP as installed in a car^^^^^^^^^^^^^Case above is 63 HP difference Gross to Net HP. The Gross Torque versus Net TQ is an astounding 85 Ftlbs tq......Crate engines mostly are rated Gross which highly inflates the usable power of the engine when installed in a vehicle......
