Sounds like everything is going to be taken care of (amen) on all fronts and I elected to go with Kooks at their suggestion. I am leaving the diameter size up to them but I think may as well go 2” into the Kooks 3” catted X pipe. Cam motion will help spec the new cam. I will be back on business.
Anyway, super relieved to know that everything will be sorted.

AHP said I could go either 2” or 1” 7/8 with the new cam (specs below) which was spec’d by AHP and CamMotion (Kip). I evidently need LS7 D port headers to fit on the Archangels (that also package under a C5). I reached out to a CF Kooks vendor so let’s see what happens there (?) but that can be done right ?
6-8 more MORE weeks minimum down on top of the 17 weeks it has been back there since I had to bring it back in Jan
. I do have faith though ! Right ?!
Hopefully this all ends soon.
New 434 Cam Specs:
234/246 duration @ .050''
117.5 LSA, 114.2 ICL (117.5+3) .639''/.630''

It is just a big swing from the other cam (.720 lift in Sig) where I was asking for the same qualities. Super nasty idle (as much as is achievable w/ excellent drivability) numbers be damned. I figured the extra cubes and Archangels (and now 2” headers) built around that other cam would give me some flexibility in that regard but whatever. I will trust the experts but it seemed like a small cam with a big LSA. I am not an expert, as long as it sounds thumpy I will be happy. I am also adding green cats to keep the smell down. This experience just needs to be over.

Thanks, I am going to go with 2” Kooks into Green Cats/X-pipe !
They will weld the LS7 flange on for me.
Hey come to think it......my old C5 LGM Long Tube headers (previously used on this build) did not have the LS7 flange. I previously used them on a set of AFR 205’s on an LS1 block. What is the deal with the correct flange ?
