need cam selection help
i have a 98 z28 with 342 gears an auto tranny with a 3600 stall conveter hooker llong tube headers texas speed x pipe glass pac's and an slp lid
i have a set of stock 799 heads i want to put on them along with a ported throttle body and a cam. this is my DD so id rather get power at ower rpms and id like to have a nice choppy idle. any suggestions on a cam? id rather not have to replace valve springs but will if necessary

look at a cam from thunder racing or Texas Speed.they both have good prices on complete cam pkgs ,and install kits.you will need better springs and push rods with the more aggressive cam lobes of after market cams.consider a 228r cam .

I think i like the 228r but is that a hole kit or is that just the cam? also it says i can change the lsa anywhere from 111 up to 115. witch should i go with?
also with that cam the 799 heads and a ported throttle body how much hp should i make at the wheels? ive herd that a stall converter will really hurt your dyno numbers is this true? sorry about the late response my comp was down.

A tighter lsa (closer to 111) will give you a choppier idle, and peak sooner with a higher peak power. A wider lsa will have a smother idle, but power will come on a little later, and give you a wider powerband

That link was just the cam only. Yes, a stalled auto always puts down less on a dyno, but generally will run quicker at the dragstrip. Like was said, lower LSA will give you a choppy idle and higher will give you a smoother idle. I would probably get a 112 LSA, that seems to be a good compromise.

so the lower lsa will give me more power at lower rpms? or will a little higher lsa give me more power at low rpms? because this is going to be the gar i drive most (my gas saver lol)

If you go with something like the 228r you will have a nice choppy idle with any of those LSA's. I talked to Texas speed and Futral about cams and with my car being an A4 they recommended me getting a cam on 114 lsa.

I'm not 100% sure why. I would assume because i mentioned running a 3600 stall and this would put you up in rpm's to allow you to run the higher LSA. Also, i think it helps with tuning.

specs are 224/220 .581/.581 116LSA
how much less performance will i get out of that cam? if its not that big of a difference id would like to save the money also will that higher lsa be better bc i have a 3600 stall converter also

The 224/220 will work, but I am almost sure you will wish you went bigger after driving it for a week or two.
With a good tune you can get more power and great street manners with a 228.
