    I have a gm Performance manifold that I pulled off my 70 and id like to know what it's worth. It's not the factory lt1 but the over the counter replacement. With that said what's it worth?
    Also should I reinstall and run it or run a RPM performer manifold? I see that this GM winter's manifold has been port matched to a 1205 felpro gasket vs the RPM that's 1204

    There are a lot of dreamers on eBay but there was 2 sold for $325 in the last 2 months.

    Is your hood flat or is it the one in your avatar picture ? Thinking the RPM might not fit under stock hood ?

    Mine is the Avatar so i would think it could fit. Just debating on running the gm or sell it. $325 is pretty good for an old gm manifold

    Bingo I would like to know also. From what I have found out it seems like the winter's is one of the best street Performance manifolds.

    A performer rpm will fit under a flat hood with a drop base air cleaner, no problem
