Asked by GuruRS7XQ Feb 09, 2020 at 08:05 AM about the 1990 Chevrolet C/K 1500 Extended Cab RWD

Question type: Car Customization

I have a 350 engine that I recently changed the plugs in only to discover that the plugs were positioned horizontally instead of diagonally in the block.
What kind of engine do I have?
High performance?
Cheap garbage?
Why the horizontally positioned plugs?
Engine IS NOT original to truck.
