    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.

    ifyou want a really lopy idle you could even go with a 110. lol. that would be crazy though. it would be hard to keep it running. 1200 idle and it still almost dies when you let off the gas fast. lol. that would be the shit. lol. but it would be so crazy powerful.

    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.

    I like 112. I think I am gonna try to find a 111lsa for my car when I do my cam.

    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

    I have a 109 LSA and it sounds smoother than a lot of 112 cams i've heard, and its never stalled on me....idles nicely at 1000rpm. It may depend on the tune.

    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)

    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.
