Cam Lobes for FI
No need to answer that last question Martin, once the heads are ported and flowed then ill fill out your cam spec form and we can discuss why you picked the lobes that you did and not one of the other commonly used lobes for FI, if that's ok with you.
Believe it or not, I'm not trying to spec my own cam (ill leave that for the professionals. I'm trying to learn why something that will be going in my car is specd the way that it was). I understand the different cam lobe profiles and what's easier on the valve train. I may be asking to much but I'm trying to figure out why someone would choose a lobe that is commonly used for a FI application over another lobe that is also commonly used for a FI application. I did a lot of research before i posted the question. If it is as simple as the persons preference after numerous grinds then I am ok with that but Martin leads me to believe that it is more concrete than that.
It may be easier be completely ready to order my cam (heads ported/flowed/short block assembled) then ask why a lobe would be used over another in my given application.
Ok ,,,,,I hear You saying You want to learn ,,,,,,,,,but asking poeple on here for answers to You're questions would take maybe 1000 years to get answered . Have You read the stickies at the top of gen3 internal engine ? There is quite a bit of information about what You're eager to learn about ,,,,,,,also I would suggest Google-ing about cam lobes and intake opening/closing events and exhaust open/clos and center-line over-lap ......etc ,,,,,then if You come back on here You can ask specific questions and then maybe You'll know enough to spec You're own cam/lobe if You study enough first . The info is there , You just need to find it . Also Car Craft ,,,,,,,,and Hot Rod mags and others like Them are a good place to search cams and cam results real world .

Martin that is exactly why i DO NOT like specs cams... people like Pat G just throw together numbers and you have no idea were the number came from or anything of that nature. I prefer tried and true cam grinds personally.. ones that have been tested numerous times...
I still think the LS9 cam would be perfect for your goals.
