I was going to follow up on your previous idea of a 3.31 rear end gear (ordered) and thought that this relativley cheap manifold would be a good match.... (2nd 3rd and 4th instead of 3rd, 4th and 5th at the track).. The ported 2018 setup has a better curve then the Boss 302 manifold and is going for less then $600, would work well with my accufab 85mm TB and airaid CAI. Might be a bit greedy but shooting for 470 rwhp with the Intake only cams! (Keep postponing the engine job since we have roughtly 30 days between races and its hard to get free time).
What I really liked was that the 2018 ported setup made more power at high rpm then the Boss manifold while giving more torque at the lower end.

The first graph stops at 7000 because the redline is based of the second graph. According to that one there is no power after 7000 that would warrant over revving a stock block.
I expected almost exactly this graph, aside the plateau around 6000. But I also expected everything to be at least 30-40 whp higher below the curve. It´s kinda nuts that this mod combo with a tune is worse than stock.
