What kind of power do you think the voodoo hyd roller 241/249 .625/.625 can make in this set-up?

489 BBC
10.2-1 comp
fully ported 049s
holley 950 HP
RPM maifold
2" headers

Also, when might these be available at Summit or Jegs? I've called them as well as some others on here and they seem to be unaware that these cams are even coming out.

About 575 BHP at 5800 as a minimum. It may make more, depending on how your 049s flow. I think it will need a 4-speed or a 3500 Stall converter, and 4.10s. But then in a lite car, it should go very low-11s, maybe 10s with a good hook.
I have just been told that the projected date for shipping is around Aug 10th, so they should have them by the 15th.
The part number for the 241/249 BBC is 60213 for a Gen IV 454-type block.

Thanks Harold! This will be a Mark VI (6) block. Do you have the part # for the Gen VI engines for that cam?

Sure-----

60223 for the Gen VI.
