    All that work for 40RWHP.

    By work, I mean heads and cam. If he is indeed selling those.
    Most everything else is very similiar.

    If he upgraded intakes...that would be a good one for you though.
    I would skip the head and cam though. Too much work for too small of a gain. If you want to get into the internals...go with a 228R from TSP for a cam. With the stock heads on your T/A, that would make more power than the LS6 heads and cam on your car.
