Re: Question on changing the cam. (DarkRose94)
Sure! ??? I actually have no idea. It might do alright because the power band isn't that high, it might work out better on a stock motor. If you are planning on doing head and intake work, you might could find a more aggressive cam.

With the 19.5" of runner length of the TPI system, you need to keep the duration around where you have it. This cam will work very well in your situation.
Good Luck,

Re: Question on changing the cam. (DarkRose94)
These specs are about half way between the stock and Hot Cam.
Its also critical to look at the lobe angle separation. This dictates the amount of valve overlap which effects idle vacuum. For a stock computer LT1, its best to keep it between 112 and 115 degrees to keep the vacuum high enough and a good idle qualities. If the cam LSA specs are 110 degrees or less, you may wish to reconsider your selection.
