These are from my '04 GTO.

Stock cam with springs. Less than 1500 miles
$60/shipped

Stock 241 heads with "484"(LS6/LS2) springs. Less than 12K on heads and 10K on springs.
$275/shipped

Stock '04 exhaust manifolds. Less than 1K miles
$150/shipped

Stock '05 GTO cat back. Only about 4K miles. This is resonator back to mufflers, mufflers and tips. Was going to convert to '05 bumper/exhaust but decided not to.
$250/pick up. Will not ship as its just too big

Obviously less for local pick up
