Cam and lifter questions!

Ethier cam will work with new lifters. Stock or not, I beileve new is the key factor here.
I used the Crane 272/284 - .454/.480 on a 112 cam in my 318. This cam idle's more mello than the comp and works well in my stock engine. I also have 3.21 gears on the OE small sized tire.
After the exhaust mods, your going to have a nice runner.
