Confidence: documented
Correct value: L34 uses hydraulic-lifter 350 hp 402 data and Rochester Quadrajet carburetion; L78 uses solid-lifter 375 hp 402 data, Holley carburetion, Positraction requirement, and different axle expectations.
Where to check: Engine build evidence, carburetor/list numbers, transmission/axle documentation, and paperwork
