My Blazer is currently undergoing an engine replacement because I was dumb... so I bought a 290hp - 380ft/lb motor that I expect will be much louder than my stock 305 was already with headers and glass packs. While I love the sound of the truck, I'm looking for a way to make my ride as quiet as possible with all the windows closed. Currently, it is so loud that if I installed a stereo, I'd have to put it at over 50% volume just to hear it... as such, I cannot hear my cell phone ring, my wife/son talking (which isn't always a bad thing) or anyone else outside the truck attempting to talk/honk at me for having such a badass truck. So what should I do? I've heard Rhino Liner is decent for deadenning interior sound, but at $450.00 to run the liner from my pedals to the tailgate, that's kind of expensive. I plan to eventually do a custom stereo system buildup, but as it stands right now, while I have everything I need, I don't see the point since I won't be able to hear it anyway. I've also used DynaMat in the past for other stereo installs, which really works great for killing vibration and distortion, but again, the cost outweighs the effectiveness. I need some good, inexpensive suggestions, and putting mufflers on the truck is not an option since I just payed to have a high performance engine dropped in it. Plus, except for the "Ford" ram air hood scoop on it (I didn't do it, I bought it that way) it looks just like every other Blazer with a 4" lift and 31" tires... so the sound is one of the defining qualities of the truck. Thanks in advance guys, and I'm looking forward to reading all the posts here about mods I can do to my truck without spending boku bucks on aftermarket parts. My next project is sealing the floor in the bed, as I think it's leaking really bad, though I can't tell because it's carpetted. After that, a good old fashioned fender chop and 33s will give me the coolest looking truck in my little town. The final project is the stereo, since it actually has to be warm for me to spend countless hours outside molding fiberglass boxes and housings for amps, speakers, and maybe even some lighting or video equipment.
