I started my 68 vette (standard 300 hp 327cui) today to make it ready for spring, but after a few minutes of warmup, the engine started to make a noise which seems to follows the rpm's.
Can any of you identify where the sound originates from? The sound is most audible at the drivers side valve cover, but sounds like it coming from within the engine
