Hey I'm new here and my dad bought me a 280z 4 years ago for my first car. I'm doing an LS1 swap on it and I was wanting to know what a good price would be to sell my l28 engine and 3 speed automatic transmission for. I have a brand new 100 amp alternator on it from zspecialties and I put a cold air intake on it. You can see these upgrades in the pics below. I was thinking of selling the set up with the stock alternator which would keep the price low and sell the new alternator separately. Does anyone have an idea of a price?
