Trash it because it used “Old and battered lifters” which makes the cam, now junk.
With a 2200 stall, you can step up in duration. 218/220@050 is about as large as I myself would go. Your gear ratio of 3.00, isn’t helpful. But if your changing gears, it does not matter. It’s just that Chrysler never used a 3.00 gear. 3.21/3.23, 3.55... yes. On the other side it could be a 2.96 or a 2.76.
What year engine/car?
Have the pistons been replaced?
