I have some ls3 valve springs (blue) that I got with a take off rocker arm package from slp. I already have springs. I would like to trade the springs for a good 85mm truck MAF. The MAF must be in working order and not look like its 100 years old. I pic would be great. I will send these priority mail if we can make a deal. I have a sale thread posted on LS1TECH for these also.
