Until you can describe the sound that you're talking about, I don't know how you expect us to tell you what it is. I have heard hundred's of vortec 350's, and I have no idea what you're talking about.

Shit...i knew this might happen but I thought you guys could catch it since it is common or atleast around here it is.

Well i can try and record a sound clip for you guys

hi im new to this forum, i had zubyc ask this question for me...im actually pretty sure this is a factory sound, even from a 350 vortec with complete stock exhaust i can notice a bit of an unwanted sound which seems to stick out a bunch more with a flowmaster or any other aftermarket muffler. i realize it is exhaust noise but ive heard somewhere that the heads of a 350 vortec cause this sound. i guess im mainly asking cuz ive heard it from just about every 5.7l vortec ive heard and ive just never known what it was or if there was something to eliminate it. i would just like to have the cleaner sound of the tbi with the higher rpm of my vortec
