LS6 cam......... I've been thinking about going to a LS6 cam and maybe the heads. I know it would cost about the same to go with a good aftermaket setup, but this car is my daily driver and the new emissions law's are getting pretty strict. I want the car to sound stock and have the drivability of a stock heads cam car. What would you guys recomend as far as doing this swap? Could I raise my rev limiter with the new cam and valve springs? <img src="graemlins/camaro.gif" border="0" alt="[Chevrolet]" />

Re: LS6 cam......... I would go with new valvesprings regardless. The stock LS1 springs are known to bend pushrods. To be honest unless you already have the motor pulled and apart I wouldnt go through the trouble. My engine is currently at the machine shop getting work done. So I just asked them to throw in the cam while they were at it.

Re: LS6 cam......... I'd recommend that you go with the comp 212/218 114 cam and 918 springs. Excellent drivability, emissions friendly and a bit more power than the LS6 cam.
If you do swap the heads, I'd at least get the LS6 heads cleaned up a bit. Midly ported heads will not reduce drivability or create emissions problem.

Re: LS6 cam......... Question: Is the 918 spring too aggressive for a 212/218 .522/.529 114° cam when talking about durability of the valve seats?
The more seat pressure you have on valve the sooner it will wear out. If you plan to put a lot of miles on your daily street machine you might need a valve job sooner than if you had a little less pressure on the valve spring. For a low mileage application you can go with a heavier spring.
For example here are some parameters on some commonly used springs:
1998 LS1 076 lbs @1.80, 220 lbs @1.32, spring rate 300 lbs/inch
2001 LS6 090 lbs @1.80, 259 lbs @1.25, spring rate 307 lbs/inch
2002 LS6 090 lbs @1.80, 284 lbs @1.25, spring rate 352 lbs/inch
Comp915 105 lbs @1.80, 293 lbs @1.20, spring rate 313 lbs/inch
Comp918 130 lbs @1.80, 318 lbs @1.20, spring rate 313 lbs/inch
Chevy uses the 2001 LS6 springs with their "Hot Cam" 219/228 .525/.525 112°
The Comp Cams 915 spring has a higher seat pressure than the 2002 LS6 springs.
Is use of the 918 spring too much for the 212/218 .522/.529 114° cam?

Re: LS6 cam......... The LS6 cam worked for me, pushed my peak HP up 400 rpms and held it nearly flat to 6300rpms. Now I can take advantage of higher shift points for more gains. Huge gains? no, better than stock? <img src="gr_stretch.gif" border="0">
