Engine 350 Base:
327ci (Small Block V8) - L46 (300hp), L79 (350hp). *Note: The product mentions 350 as a displacement, but 1967 Corvettes primarily used 327ci small blocks. The L46 and L79 were 327ci with different output.*
Engine 396 Base:
396ci (Big Block V8) - L36 (390hp), L68 (400hp), L72 (425hp). *Note: The L72 was rated at 425hp but intentionally detuned for regular fuel, actual output higher.*

300 hp to 425 hp (gross) depending on engine option.
Torque Range:
360 lb-ft to 460 lb-ft (gross) depending on engine option.
Carburetion:
