I am putting a 454 in my blazer soon. Before I do, I will be making a couple small changes to it. I am thinking of putting in a cam, lifters, roller rockers, and intake. I am going to keep the stock exhaust manifolds since I hate dealing with leaky headers. I will also be keeping the q-jet. I just had it rebuilt and it works like a dream, so I see no need to mess with it. I already have 2.5" duals w/ a x-over pipe. I also have a fresh TH350 w/ a 2500 rpm TC. I will be putting in my 14BFF (currently has 4.11's but will be getting 4.88's soon) and running the 40" Toyos. I also will be running a 1410 HAD rear shaft. The front will get a D44 8 lug conversion w/ chromo shafts and CTM joints, and a 1350 HAD front shaft. I want a good torque-y engine, but I want it reliable too. Anybody have any recommendations for a cam/intake combo? I already know I am going to give up some mileage, but I'm not too concerned about that. It will get driven to and from the trails, and maybe to a show 'n shine every now and then. ANy ideas?
