I would have had one years ago.
I like the look of this manifold but with out a dyno on it I would not buy it.
Its a lot of money but it looks like it quality built.
I have the 370 M on my car and it rocks with it compared to the stock 370 set up
if it make 15 to 20 RWHP more compared to the same set just by switch manifolds then its a great deal. Hopefully it will not loose bottom or midrange power.
On Forced induction it should rock.
