Thinking back, now . . . I could have saved myself a bit of time by pre assembling the CCV with some RTV Silicone , disconnecting the intake tube, disconnecting and tucking away my GroundingGear wires the night before.
Good luck and have fun with your install.

Daily Driving / Free Way driving will not really see this power...

Would this be helpful if I put it on my 04 287 motor? Right now I have the Rev-up lower plenum and it provides gains on the top end but removes bottom end tq. Which would be a better setup?

i have a 287 03' motor, and i already have a spacer, so if i added the modified lower plenum would i see more HP at topend? also, do you sell just the modified lower plenums?

If you don't have any other kind of plenum mod, then yes. It will provide good gains and be 100% stealth.
In fact, I may be able to modify your current collector by using a core swap to cut costs.
Here is what I have on the website so far.
Still needs work but the basic structure is finished. Not much longer.

Yes, but probably not in the comparative way you are looking for. But you also don't need it to know the difference is there. Spacer heigth Vs HP has already been mapped on the 287 engine.
See the comparative plots in the tech section of my web page. 1/4" Vs 1/2". The 1/4" spacer produces very good gains in the high end even though it is only a 1/4" lift. There is only a 1.6 HP difference between the 1/4" and the 1/2" @ 6500 RPM. And if the delta is 1.6 HP at 6500 RPM the spread will only increase at 7K RPM.
I won't say how much the collectors are machined but the plot is a good example of Bernoulli's equation in effect.

When used with a spacer yes. When a spacer isn't used it will make about 5-7 HP.
More flow clearance is better, but recent MREV test data suggests more internal volume isn't isn't necessarily better. The 5/16" produced more than either the 1/2" spacer or none at all. So there are various different optimum points and compromises at work.
Modifying the collector is one way to approach the best of both.

The excahange/core program will only work with 287 engines. Otherwise you need a MREV.
