GM hot cam hp/performance increases?
Is there any information out there on the GM LS1 hot cam with an other wise stock engine? What I'm looing for is drivability, hp and 1/4 mile gains for a M6 with just a Blackwing and cold air kit.
Any advise would be appreciated.

Thunder Racing 224/224 cam is what he meant. You need to decide what your goals are. Good street manners, emissions, etc. I wanted to get more increase across the board and have been looking at the TR 224, the Old Man Cam (also Thunder Racing), the Stealth II from MTI and the LPE GT2-3. But my goals may be different than yours.

You won't gain the full amount of extra power from a bigger cam without headers. IMO there are alot cams out there that have as good or better street manners than the hot cam that will also give you quite a bit more power. An example would be the tried and true TR224.

WOW, that was fast. Primida sent me the Sept. 2004 back issue already.
Stock LS1, 420 hp @ 5900 rpm w/ Hooker LT headers.
Here's the scoop: GM LS1 Hot Cam, 219/228, lift .525 / .525, LSA 112
50 hp gain over stock LS1 cam @ 6400 rpm, 450 lb. torque @ 4800 rpm
Thats flywheel readings with Hooker LT headers thru mufflers, stock heads.
Cam kit includes, springs & spring shims.
Add the new LS6 GM cnc ported heads & the number goes to..510 hp @ 6500, torque goes to 469 @ 5100 rpm.
WOW .................... ...................... 90 hp from heads & cam!

I had the hotcam in my ’98 SS Camaro back when it had intake and exhaust. Before number was 306-rwhp and after was 337-rwhp (that also includes the gains from an ASP pulley swap). This cam sounds incredible, but it was not very emission friendly. Also, when under 1,000 rpm the car had literally no power. Above 1,000 rpm was fine, but if anyone but me tried to drive the car, they would stall it continuously.
I liked the cam at the time, but now that the 918 breaking spring issues have been worked out, I feel there are more powerful and emission friendly cams available.
