I've been hearing the TFS STage 1 cam will work in a speed density motor. I do have this cam, but it's in my carbed '85 GT. I have heard others say it will work in SD but i am not 100% sure.
I run the crower 15511 w/1.7rr's in my car. It makes awesome power, and is about as hot as you can go with the stock SD computer. The thing idles like it is stock, and pulls hard past 6000 Specs are 218/224 .468/.486- with my 1.7's it is .500/.520 lift. Awesome torque to boot. You can run the tfs, but it is not designed for SD. Comp cams makes two great cams for SD too, I forgot the exact numbers for them though. One is for nitrous, and the other is just an extreme energy series. The crower that I have is designed to accomidate nitrous. I have every modification done to my SD motor that everyone here and elsewhere said would never work (ported heads, intake, cam, throttle body, rr's). My car still idles like it is stock, except it hauls ass now. Cool
