I've learned that you can almost identify the engine in a mid-year Corvette that has sidepipes even if the hood is closed! The smaller-horse hydraulic camshaft motors just idle so smooth through the side exhaust compared to the solid lifter'ed 327 and 427's. I'll tell 'ya though . . . . one of my favorite sounds in the world is the optional 327-350 HP RPO L-79 when it's thumping through factory side exhaust! If you ever have to do any internal engine work on your beautiful 'Vette, you just gotta slide one of the #151 camshafts in that motor. That's been an extremely popular modification for over 40 years!
