Installed one of these GM LS Stage 3 Cams P/N 88958723 in my road racing LS7 stroker. No cam card comes with, so I installed it on the pin at 108. Here are the measurements I got, FWTW;

Intake opens 0.006" @ 33 deg BTDC
Intake opens 0.050" @ 8 deg BTDC
Intake closes 0.050" @ 45 deg ABDC
Intake closes 0.006" @ 76 deg ABDC

Intake centerline @ 108 deg ATDC

Intake measured lift is 0.350"

Intake Duration @ 0.006" = 289 deg
Intake Duration @ 0.050" = 233 deg
Intake Ramp rate is 56

Exhaust opens 0.006" @ 90 deg BBDC
Exhaust opens 0.050" @ 64 deg BBDC
Exhaust closes 0.050" @ 32 deg ATDC
Exhaust closes 0.006" @ 60 deg ATDC

Exhaust centerline @ 74 deg ABDC

Exhaust measured lift is 0.350"

Exhaust duration @ 0.006" = 330 deg
Exhaust duration @ 0.050" = 276 deg
Exhaust Ramp Rate is 54

LSA is 107 deg

Base circle is 1.455" +/- .002
LS7 cam base circle I was told is 1.485 - 1.490", don't know for sure or LS3 cams etc...

So, what do you think??

Still assembling the package, no dyno runs or races yet. Gotta have a few pieces made yet, like larger crossover headers. The originals are 1-3/4 to 1-7/8 stepped, and the pipe ID is too small for the LS7 exhaust ports. 1-7/8 to 2 inch headers should be the ticket. I'm hoping for right around 650 hp or so, up from 520 with the orginal LS1/ASA cam setup.

I used that cam and it was great. It would Idle around 750-850 and had the chop of a dragster (LOL). It made great power and I have heard from Katech that it has great valve train harmonics.
