67lemons,
I can’t even begin to advise on the quality of parts these days. I have the China and Mexico lifters in mine. No problems so far. Be careful with the ones you ordered. Make sure they are the correct design and not a superseded later design. You can look back in this thread and see what I’m talking about.
I will attach a photo of my Comp Cams cam card installed in a 73 455 block. I will also attach a Lunati cam card that Gtobob67 installed in a 73 455 also. He posted about 3 pages back with success and some miles on his setup.
By the way down to 3 Sets.
Thanks,
Stan
