I ran the big block Erson TQ20 “The Performer” cam in a big heavy 70 D200 w/a low compression 400 (3.38” stroke) Auto, 3.54 gear, 33” tires back in the mid 90’s. Was a great cam, very mild rump to the idle, strong for a daily driver, saw no problem with it or shortcomings. Prior to the internet you just slapped em in and that was that. Now there’s a little bit of revisionism I think. Sure you can do better, but you have it, it’ll work great. Keep in mind It doesn’t stop working or being good just because theirs better options today.
