Hi,
I'm planning to rebuild my truck engine this winter and have been searching the web for information. I've been lurking here for about a week and have found more than I even knew I wanted to know. In most of the other forums the informaion I was looking for consisted of several different and often conflicting opinions without supporting data, was hard to find, or just didn't exist. Not so here; the more I look the more I find.
My project is a stock 1986 GMC K3500 w/ smog choked 350, TH400, NP205, and 4.56:1 limited slip. My objective is to rebuild the engine for substantially increased low end torque and top end HP, replace the auto with an SM465 4-speed, still pass IM testing, and of course, stove bolt reliabillity. My engine goal is 300 ftlb @ 1000 rpm and at least 375 hp @ 5000-5500 rpm. I know, I know,,, 375 hp doesn't sound very exciting. But, it's perhaps 150 hp more than stock and with a bottom end that should pull like a mule team. I think it qualifies for "High Performance" in it's own right.
Anyway that's me. I'm beginning to formulate a plan for the build and I'm sure I'll have plenty of questions. There's one nagging question that's been running around in my head for awhile now but I'll ask that elsewhere. Still digesting the tons of information you already have on here. Thanks for the putting this great site together.
