Mine was a little shorter on exhaust, .596 lift. Very happy with it,

I've just got mine running n/a right now. Only made 487 rwhp that way. Thought it would do a little better but I know it's for boost.

550 engine, assuming stock intake and TB would seem about right. I have a MSD and dunno 95 ish TB really not needed for boost, but probably worth some HP NA. The 118 LCA is going to be down midrange torque and the 4 degrees of advance will cut power off the top end, but like u said the cam is for boost.

I have a msd intake with 95mm TB, 1 7/8 headers hooked to stock exhaust. It lost power and torque over the stock cam everywhere until around 5k. I have a Lt4 blower set up ready to go on it. I had my heads drilled so I don't have to run adapter plates. I thought it would make a little more power. It made 451 bolt ons.
