OK, that may be overstating the issue a bit. Anyway, it's a 1-ton with a 454. It had a bad piston in it when I bought it a couple months back so I overhauled the engine and installed a Comp 256 cam. I chose the 256 because the truck never sees more than 4000rpm and I wanted more torque for towing. It runs well now and has decent power but now I'm thinking of what I can do to maximize what I have for minimal investment. My thinking is the best way to take advantage of the engine in general and cam specifically is to open up the exhaust. Right now it has a 2-1 design with 2.5" pipes off the factory manifolds that merge (rather poorly) into a single 3" pipe, then hits the muffler and cat back by the back axle. So my thinking is to leave the factory "log" style manifolds on but have the crappy pipes replaced with mandrel bent pipes into a true "merge" collector, then run into a good muffler (I'm thinking Dynomax) and ditching the big, heavy pellet-type cat for a newer free flowing cat. I'm hoping all this will give me another 25hp or better. If I can get 25hp out of it, plus a little nicer sound and maybe even slightly better economy it will be well worth it.
So do you think my expectations are unreasonable?
