Well I contacted a chip manufactuer, and they told me before I order a chip I should know what cam I will be using. I am running a 91 EFI 460 and am curious as if this will be ok and not throw off the speed density computer?

I also have a twin BBK throttle body on the way along with a Adjustable Fuel Pressure Regulator. Will this cam run fine? Will I want new springs with it?
i can't tell you if that cam will work or not - you need to call the cam help line of a reputable cam grinder. but i would say get new matched springs for sure. you didn't say how many miles are on your current springs, but anything over 60,000 miles- if it is coming apart- might as well replace them. and since the cam is larger than .500" i would say get the correct matching springs anyhow...
let us know how it runs.
Called up comp cams a hour or so ago. They have a cam made for the SD computer. $194.00 and he said I will need matching lifters which is another $84.00. Am I gonna wanna get springs also or will lifters+cam be fine? He said this is all I need.
