Being a lake bum in Texas
wont be starting this for a few more months but it will for sure be starting in oct-nov time frame. motor is currently in my k30 bolted to a th400 and np205. truck has been used as a workhorse and play truck its whole life so the bed is not in the best shape, and the cab corners/rockers/doors/fenders are all pretty rusty so will probably be pulling the drivetrain out and putting it into the next rig.
plans for the motor and requirements. staying carb, very simple and reliable, not to mention they are cheap and easy to work on. aiming for at least 500hp and 500ft/lbs of torque, though would like to be closer to 600 if possible (see other requirements). reliability, not going to be racing this motor, will spend the vast majority of its time in the low-mid rpm range. plan to keep this around for a long time so reliability is very important, dont want to have to rebuild this thing every few thousand miles. fuel economy, its a big block going into a crew cab pickup, suburban, or k5 blazer so fuel economy will not be great. was getting 11-12mpg around town (before the carb had to be replaced) with 35" tires, if i can get up to 14-15mpg i'll be very happy. budget on this project is a few grand, though nothing extravegant lol. also want this to run on pump gas so compression ratio cant be too high.
i'm fairly new at rebuilding a motor so input is greatly appreciated. one of the options that i'm considering is having the block bored .040 over and making it a stroker, should put it about a 490ci if my numbers are right. not sure which style pistons to go with (flat, dome, etc) or which crank would be needed.
for the top end i know that the stock intake manifold is pretty restrictive and the heads leave alot to be desired. can the stock heads be worked to meet my goals or would i be better off replacing them? i found this kit on summit for a decent price http://www.summitracing.com/parts/EDL-2095/ that could work, though if there are better ways to go my ears are wide open.
fuel system. the truck has a mechanical fuel pump, should i change over to an electric pump with a regulator to keep it down in pressure for the carb or stick with the mechanical? the carb i now have is a 800cfm edelbrock thunder series avs, simple to adjust and for the angles that i encounter offroad its one of the better ones to go with.
exhaust. will be getting a set of headers, however with the amount of options not sure which type to go with. thinking long tubes because of the torque benefits and the fact that i have the room for them. what size primary tube diameter though, 1 3/4" or 1 7/8"? and the collector, should it be 2.5" or 3"? will be a dual exhaust system with an H or X pipe if needed.
all input, ideas, help greatly appreciated.
