ls9=Gt-7 lingenfelter cam for $159.00

Holy crap.
Some one will be using this info for certain. This will be my next cam for sure. You will need a few things to make it work. See bold info at the bottom. Not sure how much the extras are but it cant be too much.

I took the info below from lingenfelter.com
This is the GM factory 2009-2010 LS9 ZR1 camshaft that works excellent in many supercharged or turbocharged applications. The LS9 camshaft is 211/230 @.050 valve lift and .558/.552 lift with 1.7 rockers and a 122.5 centerline.

Before the LS9 was introduced LPE used the GT7 camshaft that John Lingenfelter designed in 2001 to be the perfect camshaft for boosted LSx applications. The GT7 was 208/230 @.050 valve lift and .554/.546 and 121 center line this camshaft produced excellent power and still had great street driveablity. In 2009 GM introduced the LS9 in the C6 ZR1 supercharged Corvette engine. After comparing specifications on the camshaft and finding out how economical this is due to it being mass produced Lingenfelter discontinued the GT7 and started using the LS9 in supercharged or turbocharged applications.

The LS9 camshaft is a 3 bolt design and will use the Lingenfelter 3 bolt cam conversion kit if you are installing it in a single bolt application like the 2007 – 2010 LS2 or LS3. If you are installing it in an earlier LS1 or LS6 engine with the cam sensor at the back of the engine you will need a 2005 LS2 front cover, 2005 1x cam sprocket, camshaft extension harness, 2005 LS2 chain dampner.

I would have reservations with putting the LS9 cam in a truck, boosted or otherwise. I'm not sure why LPE considers this cam to be equivalent to their GT7. Yes, it's specs are similar to the GT7, but the two cams would have different personalities in a vehicle. Their duration, lift, LSA, and exhaust timing are similar, but the intake timing is way different. The GT7 cam has the same intake closing event as a Z06 cam. The LS9 cam closes the intake valve 6º later. That's a big difference. The LS9 cam is intended for lightweight vehicles that rev high. Put it in a 2½ ton truck and the bottom end goes away. To make it usable in a truck, it would have to be advanced at least 4-6º.

at first 159 bucks is good price then you have to pay for the conversion which will cost you a few bucks more like least 200. so now your 359 for a cam. at that rate you can buy a custom or another cam suited for you

Yeah. It really doesn't matter though cause I can't buy one either way. No way possible after a level 5 flt 4l85 with PI vertor. I can't buy anymore truck goodies for at least a year. I like the thoughts posted about the cam though. I don't want to give up any low end power.
