how much would it cost to have my ls built??? i want to use my stock crank but get performance parts for the rest of the bottom end and new cams, valves, springs, and retainers. oh if theres anything im missing please feel free to add it on thanks.

 

There's too many variables. The quality of parts, labor, amount of time, extent of rebuild, and type of shop will all play a role in how much it's gonna cost you.

Since only YOU know what you want from your motor and what your goals are, I suggest you check out a few shops/websites/magazines and get some prices on the parts you want. Call up a engine rebuilder and ask him how much he charges for labor on, for example, a bottom end rebuild.

Your question is like asking "How much should I spend on a computer?"
It's not specific and you'll get a different answer everytime.
