[1970CUDAAAR]

I'm new (past 4 months) to the forum. I own a 1970 CUDA with a 440 HP - with a Holley Sniper EFI -with a HEI distributor.
I'm getting all kinds of number on how to set the timins - is the following OK for a street car with is Moapar extreme energy cam (Lift = .477 INT .480 exh - Duration .268 Int .280 Exp):
Initial timing on balancer 8 degree
Timing appearing in the Holley manual = Idle 18-34 - Cruise 32-44 - WOT 28-40 = which one is good for me

AFR - Idle 14.0 - Cruise 14.5 - WOT 12.5 (suggested by Holley)

Thanks!

If you post this up in the Engine Issues forum you will probably get more responses.

Welcome to the site from Arkansas!
As Lee said, you’ll get some help for sure.
Initial timing sounds a bit high to me but, don’t know with efi. I do know voltage and grounds better be as good as it gets with the set up.
My buddy just removed the same system and going back to carb. They just couldn’t get to perform right consistently. His job keeps him away from the car sometimes 6 months at a time. ?? Lots of guys love em though. Good luck to you and glad you joined up.
