stock cube cam help
stock cube cam help ok im doing forged 346 ls6 intake 317 heads and 78mm front mount , trying to figure out which cam would be best , i was thinking of going with a ls6 or speed inc tu1 ,i have a255 pump and 60lbs injectors this is my first turbo car and i just want to make sure i build it right with what i can , anyother cam suggestions would be great thanks
I can't remember if it's the TU1 or TU2 I have but it's the one that's 225/225 from speed inc. awesome cam for a 346. My car with a large frame made 756/781 at 15psi with my old 80mm.
Still have the same cam in the same motor with a large frame on it now. Made 781/775 @ 9psi. All on 93 octain. Gonna push it as far as it will go

I run the tu1 cam in my car and like it. My build is very similar to yours so I don't think you'll be disappointed. Car is really responsive and spool is really quick.

68mm turbine(TC78) with .96AR. Stall is a 3600 circle-d multidisk, 3.73 rear and the car is full weight at about 3600lbs. The only issue I have is due to the small turbine wheel I choke a little up top, but this car has such a great midrange and spools so damn quick.

Verdad Gallardo It wouldn't be my choice though for a bigger turbo, but with the small turbine you have, and an early evo opening you are able to spool your turbo very quickly.
That said I was actually asking the OP what his car weighs, stall speed and rear gear
Fbody you seem to know your stuff on reading a cam card. Maybe you can calm my nerves a little on this swap.
I'm running a 4.8L with magnum 76/67 .96 t4 at 21-22psi and 50 shot of nitrous with a ls6 cam. Truck pulls very strong to 6k then goes flat.
Would you trust this cam with back pressure i'm likely seeing with my setup? Looking for 3500-6500 power. I'm looking for an extra 50-75HP to push closer to 9's 1/4. I leave on a transbrake and 2-step usually at 3400, but can go higher.
I have the cam in hand, just be up in the air if this is a good move with this turbo.
Thanks for your input bud and any others who care to share their thoughts.

bump to OP, did you decide on which cam your rolling with..
Im in the same boat, can't decide between the TU1 or maybe even a custom one a slight bigger, but not as big as the TU2..
