who reacons that this manifold ( ZR C CNC Performance Intake Manifold Block) actually works at increasing the performance, who has one that the think it made a difference or if any? and rate it on a scale of 1-10 (10 being the increase and 1 being the not much difference). it does have its good qualities with the nylon and aluminium casing so it cant be crushed when the carby is tightned up

There are many companies coming out with aluminum isolator blocks with claims of more horsepower not to mention no more problems with plastic ones warping, M&D and Top Secret to name two of the others.
What I do see is better port matching between the carb and the block but if plenum length is helping, I don't know yet.
Once I get my gas boat dialed in I'd like to try out one myself to see if there really is any boost to be had.
