Which cam to go with for a D1SC

CHRISPY, I have read that the Fast is good to 20psi or so and i dont see myself pushing that much psi. If I forge the motor with 9:1 pistons and keep the stock cubes what kind of power would that give me with the Z06 cam? If that would give me around 700whp then i would be plenty happy with that combo, but if I would need to go to a more aggressive cam to see 700whp then that is fine also.

Tony from AFR posted this up today, take it FWIW.

I ran a FAST 90/90 with the Z06 cam for a while and picked up nothing. I didnt have any issues with it, just a lot of money sitting there that didnt do anything so I sold it off. I would like to see just a straight intake to intake swap but the FAST seems to be doing OK. I may try another one someday out of curiousity.
Dont count out those 347s with a turbo or blower

Bigger cam eases up on the mid range cylinder pressure some, while it has hurt my 60 foots some, the ET and MPH and picked up overall so its a wash. But (knock on wood) the same head gaskets have been in the car all year. I was pushing about a quart here and there with the old cam/D1 (222/228) and was enjoying some spectacular wheelstands/60 foots but as soon as I swapped cams no more pushing water, even with the F1A pullied up.
Time will tell though, still not sure if I liked the big hit off the line or the power really coming on hard 30-40' out more. I'm never to confident about the head gaskets so I dont like to say anything really fixes it just yet. But a cam swap takes a couple hours and a cam doesnt cost much so I like to experiment a little.

OK I think I will go with a blower cam with a little lope, you convinced me with "you can hear the blower whine change notes with the cam lope" so know the question is which cam has a little lope and is very streetable? also if i change the pistons and rods do I need to balance the crank to the new set up or does it really matter?

That 224/224 114 should work out fine, lots of other blower cams in that same area that sponsors sell. Just dont go too big if its a daily driver, I would still use the Lingenfelter cam thats similar to the 02 Z06 cam or find a Z06 cam somewhere and put good springs on the heads to start out with. After you get everything else going right and get the car tuned where you can have some fun with, then swap to a larger cam and it will be like having a new setup

kp, Yes I do want the car to be very streetable so I will not be going to a large cam, but i would like just a little lope, just enough so that you can kinda tell it has a cam. Will the Lingenfelter cam do this for me? Also do i need to balance the crank if i change the rods and pistons?

Everything should be checked for weigth and the crank balaned.
The 222/228 115+2 XE comp cam I ran had a nice little lope and was very easy on springs (.566/571) lift, very good idle vacuum and I was using the single 918 spring. It made great power all the way to 7000 rpm.
But there are tons of similar cams out there, maybe call Bob at EPP and see if they offer a smaller cam, Slowhawk and the guys a DEZ can help you out as well as many others here. Dont stress too much about it, anything in that 222-224 intake and 228-230 exhaust on a 114 or 115 will be just fine.

Power, idle, sound, drivability?
