Aslo which manifold could i get the most horespower out of? Oh yea its carb if that helps! And which shift kit for 4x4 would you guys recommed its for a c6, im looking at a transgo one right now but just wanted to know what you guys think.
you didn't say what year truck,but hedman makes a 2" outside the frame header with 3.5" collectors.i've got a set of these on a 79 bronco.intake-alot of stuff in your combo would have a bearing on which would be "best".shift kit-for an "off-road only" truck i'd put a reverse manual valve body in.i have one and still drive it on the street.
Any rules about flipping the headers upside down and running them through the hood? If you don't want to do that I totally understand. Mud trucks with the headers through the hood cut down on mud getting in the collectors and gummin up the system. I would say to run a 1 7/8 primary to a 3 to 3.5 collector. That may give you just enough back pressure to keep from slammin the valves shut.
You asked about manifolds I assume your talkng intake, well there is no answer to that without knowing the specs on the engine expecially the cam specs nor can a good estimate be made without know exactly what type of offroading your doing. I run a victor style intake, works great in my application (very few apps that a high rise single plain intake works good offroad) but it would stink for a rock crawler, conversly I couldn't get away with a performer or stealth intake as it would kill my power. And actually this does apply to headers too. my primaries are 2.25" with 4" collectors and are almost too small, but it would kill low end on an engine use for running rocks or trails. So we need a little more info to give an informed and correct recommendation pleas.
a little more info is need as to what type of mudding your doing. is it trial ridding to mud holes or is it for mud drags??? big cams usually kill your vacume so brakes dont work the greatest at low speeds which you usually need on trails. but if your trails are pretty flat and you dont need the brakes as much you can get away with a bigger cam. also you may not have to buy a new cam just pull the one you got and get the numbers off it and im sure you can find what cam it is. may just be the one you need and you just saved yourself some money to use elsewhere.

This would be a good time to check his timing chain and see if he has a 0 or retarded timing set.
