I can’t wait to read the before and after results of a roller cam.
I'm getting close to switching to a roller cam in the big block!

Once you go roller, you’ll never go back to a flat tappet. They have their place in low buck builds and restoration engines and such but in a performance engine, roller cam all the way. Sounds like you’re in good hands with this one.

Since my other engines have held together with the milder cams and springs, (Also with vintage parts) they will stay that way.
THIS car has always had the biggest camshaft, stiffest springs and highest compression of the cars that I have. It is also the one that I drive the most and unfortunately, it has had 3 flat tappet cams go bad out of the 5 that I've used in this block. At a glance you'd think that there is something wrong with the block but you have to consider all the factors. High performance parts are under a lot more stress than 318 parts and that stress can reveal weaknesses that are not usually seen in milder engines. The roller design should alleviate the risks that I've dealt with for years.
