lift is .612 on intake, .615 exhaust.
I just happen to have this cam and was wondring what ya'll thought about it in this app. It is hydraulic. What cam profile would be reccommended? Why?
Thanks all

That cam is not going to really start to engage until have in the upper 4K RPMs. I have a 236/245//598/608/115 in my 402 and it starts to engage about 3600. As Fireball said, that cam is a bit too big for a 408.

I have had much bigger cams with smaller cudes and turbo. And it works just fine......seems a lot of people/shop on this site shy away from bigger cams.....most racers/engine builders I talk with use use large cams with their F.I. combinations....so I would run it and se if you like it..

Verdad Gallardo According to his sig, his car is a daily driver so that is why I made my comments. If the car is a pure track car, then I would definitely give it a thumbs up.
I know that many have different opinions. Based on daily driving, what would be an optimal profile that would fit?
I'm about to pull the trigger on this build and would like you "vets" to help me make the best choice in this scenario.
Thanks in advance

Want to talk drive like stock I run the lingenfelter gt7 which is nearly identical to the 2005 to 2007 z06 cam. I have the 1.8 yella terras to bring lift up to .590 or so. I didn't want any lope on this cam and don't have any.
The cam might not be optimal for max power or track but my car is 99% street car and driveabilty was big priority.
Specs on the gt7 are GT7 208/230 .554/.546 –121CL
Ling does use this cam a lot even on their bigger cube builds. Seen a ton of theories over the years in this forum with every variation put forward. Normal split,reverse split, no split, high lift, high lsa ,lower lsa.
Seems like pretty much anything can work decent with FI. I also didn't want to go past 600 lift even though have 8019 springs in my afr 225s. High lift springs means more frequent valve spring changes..a pain in the *** on f bodies and more chance of valve float. How well my cam and combo works will hopefully be determined with some dyno times this coming season. Just got the combo running end of last season.
I would also think at the higher durations and lifts you would have to be much more careful of your ptv clearances.

When we say "bigger", we are talking lift. In my ignorance, what would "to big" be in a street app? Does bigger mean mearly more chop and less drivability, thus inversley, does smaller mean less chop and more drivability? Where is the happy medium? I know this is preference based, but there must be some consensus. Max power/max drivability in a street driven performance car = what cam profile???? If anyone is interested, the cam I pull will be free to a good home
"Big or Small" usually refers to duration. A large duration cam will be limp in the lower rpms and will make power in the higher rpms wanting to rev. Not good for a turbo car. For a turbo, you want moderate duration and a wide lobe seperation for your cubic inches.
