I am not an engine guy. I know of a lot of things that can be done under the hood and I can swap out basic items, but when it comes to the nuances and inner workings, I lack a full understanding.
For instance, I know that changing the camshaft, something I wouldn't attempt myself, is how some guys get that aggressive, loping sound from their engines. And after a little reading I know that a camshaft upgrade can go the other way too, making for an even smoother running sound at the cost of HP. It is also my understanding that you don't swap the camshaft until you have done any other mods you have in mind (intake, exhaust) because the type of camshaft you go with will depend on those factors. Beyond that, it is a lot of technical engine jargin that leaves me at a loss.
For what I have in mind, I would like to eventually give my Tahoe a slightly more aggressive sound, but not the full loping some guys go for. I want it to be just noticeable so that another car person would recognize that something is different, but others might not notice Some say that you can get a .5-2 mpg gain from intake or exhaust upgrades and I would like to think that the cam upgrade would negate this. What I would like input on is: Is it even worth it? Would I be able to get that 'just noticeable' sound before taking a big hit in mpg?
Thanks.
