You can get a lot of the products that you would need from Texas Speed Performance. Also if you plan on doing the install's yourself there is a good website called LS1Howto.com that can help you a whole lot.

If you want to get a lot of lope/chopppy idle out of your cam make sure you get one with a 112 degree lobe separation angle, 112 LSA.

yea a 110 LSA would be a very lopy cam, too lopy imo. The 112 is a little too lopy for me, but a 114 is not enough. But all this is IMO though.

Full bolt ons and invest the rest in a very well setup suspension. The cars already have enough power to make them fun. If your looking for more power throw a 228R in there and youll have plenty to mess with. That cam has a great powerband, so if your into autoxing and corning, thats a great choice

Went shopping today, bought a extreme energy high lift comp cam 222-224 with a 112 lobe center, springs,roller rockers,retainers,locks,chrome molly push rods, guides & gasket set for $1500.00. I think I got a good deal + 500.00 for install & tune. What do you think?

for a fun street car just do some bolt ons, a sweet sounding muffler. Strano performance for the suspension ( makes the car look level and handle ooh so smooth)

Current best: 10.60/126.8- 1998 Pontiac TA WS6
My cam right now is 114, but I'm wanting to go 110 to make more power on top. Years ago, I had a small block chevy that had a cam that was ground on a 108. It was very lopey, but had no problems idling at 900 rpm. You need a pretty big stall if you do something like that. Thunder racing has a t-rex cam. Its pretty radical, and ground on a 110. But of all the cams I've seen thus far, I am impressed with that one the most. TSP has the magic cam series, those are good also. On a '98, when you replace the heads you will probably end up replacing the valve covers also since they are different from the other years. Most aftermarket heads use the 99+ valve covers, and you will need a bracket to mount the coil packs as the 98 mounted directly to the valve covers.
