That sound like alot of cam. I am thinking of going with a stroker myself but am thinking of a much smaller cam.

Who's heads are they?
You have to remember when using a bigger cam to achieve max results you need more air. It would suck to spend 400 dollars on a cam plus labor to see a small gain due to lack of air. It is extra hard on a bigger cubed motor.
I think the cam specs you listed sound very good. The duration could be a little different but looks great for a N20 car.
Just my oponion.
Another thing you will need to consider is PV (Piston to valve) clearence.
Depending on the pistons and on if the heads have been milled you might run into a problem there.
Defentially take that into consideration and do some research to find out if that cam will work. I know comp will custom grind something for you, and Thunder might as well.
Good luck
And yes I would defentially have the car retuned after a cam swap.

TR, MTI, LS1Speed and some of our other sponsors can get it custom ground from comp.

Retuning after a cam swap generally makes sense.
