What is the hp on a 1974 Chevy c20 pickup?

The horsepower of a 1974 Chevy C20 pickup varied greatly depending on the engine option. Chevrolet offered several engines for the C20 in 1974. There wasn't a single horsepower rating. To know the horsepower of a specific 1974 C20, you need to know which engine it has. Common engine options included:

* Small-block V8s: These ranged from around 145 hp to over 200 hp depending on the specific model (e.g., a 350 small-block could have various horsepower ratings depending on carburetion and other factors).

* Big-block V8s: These were significantly more powerful, often exceeding 200 hp. Again, the exact horsepower would depend on the specific engine (e.g., 454).

* Inline-6: These were less powerful than the V8s, typically in the 100-140 hp range.

You'll need to check the vehicle's documentation (like the owner's manual or the vehicle identification number (VIN) decoder) or look for an engine identification number on the engine itself to determine the exact engine and its horsepower rating.
