This is what i have found so far.
Isky-284/292 .736/.675 110
Crower-286/290 .720/.711 108
Bullet-268/274 .729/.693 108
Shnieder-276/284 .749/.730 110
12:1 race app with less than 750m/season. Stage V heads and 2x4 intake, 5500 stall/727 4.10/28" tire 3300#, race weight, foot brake. what are you guys using with good results?
 
With that many cubes in a race application, I wouldn’t hesitate to run something like the old R296 roller cam.

Correct. One question regarding your combo, why aren’t you running a trans brake?

I had one at one time. sold it. I only go to the track for a paper trophy. Here's another cam that looks good too, 280/284@50 on a 111. Dynomation5.

The transbrake would definitely help the paper trophy. Is this a new build or just upgrading an existing combo?

It is a brand new build. I am new to the Hemi engine. I got so tired of having to push a a button to back up. I am staying foot brake.

276/284-112 in at 114 works the best. Gives most low torque and best peak and average numbers where i would like them.

What lift you running and what cylinder head?

That 572 combo was .750 lift with the Edelbrock cast Mopar Performance head. My current combo is a 540 with Edelbrock Victor heads, twin turbos and a smallish street cam.

Twin turbo, wow, i bet thats fun to drive. Any time slips yet? Schnieder racing cams spec'd the 276/284 grind, but on a 110. According to my program the 112 works better. I tried the 280's in the program and they just killed torque for peak hp.

I’m figuring out the EFI and creeping up the boost. It’s been 5.70 in the eighth at 129mph at 3950#. It should go low 5s next year.
 
I have a 572 w/ old Mopar Perf. Heads (Ported) with a cr
cross ram, 12.5 to 1 3600 car. Crane built me a 800-809 288-296 @.050 on a 109cl


The cam I was running when it was a 498 was a 785-760 / 284 - 286 @.050 on a 110cl.

What is your stall speed and rpm? I know that's a lot of spring for the street, but do you think that could be driven on the street at all with that duration and lobe sep of the cam?
 
I got ahold of Tim at Bullet. Cam is on order and he had some cores. He suggested a 308/275/193 on the intake. 275/278 on a 110 in at 106. Says it wont give up much over the next more aggressive lobe. Tighten the lobe spreads because the flow ratio was 75% or better.
 
Mine 528" is over .800 and I drive it on the street. .805/.815 /312 / 114 LSA. With a PTC 9" 5600 converter and 4:10 gears on 315 Drag Radials.
