    what power expectations?

    i finally said the heck with it and bought a TSP shortblock 347..yes its cheaper than turning a crank honing a block and buying forged goodies with arp bolts etc.. so heres the build and i am curious what yall think it will make power wise

    TSP 347
    LS6 intake
    80 MM BBK TB
    chromoly pushrods
    comp lifters
    SLP dbl roller timing chain
    LS6 oil pump
    NGK plugs
    MSD wires
    Lunati 234/236. .050 .544/.545 @ 110 LSA
    re worked stock re worked i mean 3 angle valve job and new seals LS6 springs, new lock and retainers and cleaned up some of the major porting just a good cleaning

    and how do you tell if your knock sensors are crap? granted my motors apart but i dont know what they cost..where to get old ones are kinda rusty and look like crap..

    anyways thanks for your help!! the last combo gave me 385/395
