Bought from a fellow member who didn't have the cam card. Matt @ TSP said they don't have one for it since it's an older grind.
Numbers on the cam are:
-RRSI 231-237
-U1EA 112
-232307 (in smaller stamped numbers)
Any help is greatly appreciated. Anything, advertized duration would be most helpful.

I'll check my card tonite when I get home. i might be running same cam, not sure if my lift is the same. I think my lift is .589/.595 . i verify the cam card.

How high do you want to spin your motor? On a 110 ICL that thing should peak around 6600-6700 rpm. I would install it on a 108-109 ICL unless you want to spin it that high. Naturally the LS6 intake is going to try and force peak power around 6300 though. I would say:
LS6 Intake: 108-109 ICL
Fast 90: 110 ICL
LS6 Intake: 108-109 ICL
Fast 90: 110 ICL

The LS6 intake is ported, both runners & inlet. It shouldn't drop more than 5 kPa MAP pressure through 6700 RPM. Will confirm this once running. My old cam, before runner porting dropped only 3 kPa up to 6400 RPM through the larger inlet. In any case, will modify the intake as needed to run on the 110 ICL. Also upgraded springs to 8019's & went back to 1.7:1 rockers so that the engine could be spun a bit higher.
Thank-you for the comment, though. It is good information.

That's really not bad. I didn't have a need to port the runners (& would never suggest to for a mild cam) before installing this higher lift, longer duration cam. The mild runner porting should keep the air speed from getting too fast, & therby dropping the MAP; if it is the runner that causes the issue (after having opened the inlet & an 85mm TB). I think that it is, based on all of the intake testing that I've done on my car. Am hoping to start the car tomorrow or Wednesday. It may be a few more days after that before a hard pull can be done. Will post again after...
