You don't have a vacuum secondary carb. Your carb is mechanical.

That cam has more in common with an L88 race cam, than a street cam.
There is no taming it.
It needs to come out.
You should talk to your engine supplier.

So it appears that this cam definitely isn't matched to this motor. Here is the Dyno with the big cam in. The HP is dropping off around 3600rpm's. If the cam range is 3200-6200 shouldn't HP be going up in this range?
