Help with hotcam?
I am extremely pleased with the results from the cam. Results in the sig... and there's more to come as Superchips isn't done tweaking the PCM for me... I just need to get my diagnostic logs to them for interpretation and get the new program uploaded. I'm expecting around 390+ (hoping for 400) on the stock heads. The hot cam isn't radical, but it sounds it... it's very street friendly and it won't break the bank either... I got mine on a GP in the kit in March 2001 for a steal. Bang for the buck, it's a good way to go. Many people will tell you it's not... and, well... if you're looking to eek out every last horsepower from your engine, it's not the cam for you. If you're looking to gain some power, and have a streetable cam that's fairly conservative and very daily-driver friendly, then the HC is for you.
All in all, I give it two thumbs up.

I think SDPC GM Performance sells them cheap. The stock rockers are fine.

Thanks, Tim
I have the hotcam+lid+SLP longtubes kit+catback
and passed Dallas TX OBDII inspect, ( new improved
strict $40 instead of the $12 last year ).
I have a M6. I have drilled my throttle blade to
15/64" and added a .022" shim to the stock setting
of the idle set screw. ( that way I can change things and always get back to stock ). The shim and
drilling was to cure idle problems with idle with AC
on during the summer.
Performance, the car can be scarey above 3000 rpm.
I use this car on vacation. July 2002, latenight
crossing lousiana at 75mph cruize with AC on
29.3 mpg at at 200 mile run. The majority of trip
is was more like 25 ish.. City .. mostly 13-17
depending on your bad habits.
I have 20K miles on this setup and im happy.
There are stronger setups, but I belive with
performance you degrade reliablity, so find
something your comfortable with..

You do not need to reprogram for the cam. You will from time to time receive an SES light if you allow the car to idle for periods longer than 90 seconds. If you find yourself idling for long periods of time, a simple "blip" of the throttle to 1,000-1,200 RPM's will confuse the PCM and prevent it from misdiagnosing the cam's lope for the P0300 "random misfire code". After the first month of having the cam, it became second nature to blip the throttle to prevent the code from popping up. If you do get the SES light, it will go away in a couple of starts and does not degrade performance whatsoever. I pulled data logs using Vehicle Explorer (an Autotap like program) and saw absolutely no performance degradation due to the P0300 code whatsoever.
After finding out what the speed shops around here wanted for cam installs (they ranged from $350 for an "under the table" deal to over $700+) I bought the Helms manual ($120), a spring compressor from NAPA ($49), a 3-jaw puller from Discount Auto ($20), and did it myself. It took me 13 hours to do with some buddies and a whole lot of time spent bullsh!tting. If you're mechanically inclined, patient, and even mildly know your way around an engine bay, you can do it yourself. I downloaded a couple install documents from LS1.com in August 2001 when I did the swap. They had all the information I needed, but the Helms Manuals were useful for supplementary information as well as documented torque specs.
When I fired the engine up, it started right away. It found rock solid idle and had no problems whatsoever, and has been an extremely healthy motor ever since.
Since doing my cam, I've done about a dozen installs (and made some $$$ doing it) and can now perform the cam swap in just under 7 hours.
If you're not mechanically inclined, or are bad at reading or following directions, find a reputable speed shop and invest the cash. You can expect to spend at least $600 to get the cam in there.
