The top ring land is usually the weakest link, it’s not boost friendly but should be fine in the 8ish psi range with a good tune.7-8 lbs. Trans will be the weakest link but if you go beyond the canned Diablo tune Procharger includes with it’s kit.The trans does its torque induced downshifting which makes a dyno tune rough but it can be done with HP and a trans tune.
If it’s the 8hp70 it’s not a weak link, they are usually good for 600whp as long as you keep some torque management. If you take all the torque management out that’s when you’re gonna have a bad time.
