292/508 question

Will adjust cam advanced to get back some torque and timing will go 18° or even up to 20° or 22° initial and 34 total to avoid ping. I also have a 4200 stall dynamic 9.5 converter waiting to go in. Or I may keep the 9.5 FTI converter 3400-3600 stall not sure which to use.:eek: trans is the 727 with pro street turbo action valve body.:)
