I've also never seen ls parts cheaper than 307 parts. I mean, it's $7 for a fuel pump, $50 for an alternator, $15 for a water pump.
Original mechanical parts for a gbody are much cheaper than anything ls oriented, with way less to break.
I can't wait for all the ls fanboys to be stuck with hacked cars and dried up electronic parts choosing between poorly working Chinese knockoff aftermarket and nothing.
Meanwhile oem guys will buy a $15 carb kit, $3 water pump gasket set, or $9 in alt rebuilt parts and just keep their old junk, worth a premium to collectors as it's original and not hacked, on the road.
