FWIW, my last sft was a XX spec'd by & sourced from Dwayne for my old Stage VI combination. I had Schubecks at the time, but would probably go w/ standard EDM lifters today.

Still not sure on whether nitriding is a "no brainer" at this point.

Why risk cam lobe failures on any flat tappet cam when you know the history of failures since zinc was removed from most engine oil work


Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Use good race oil like Penn Grade and add a small bottle of zinc additive for insurance. That and EDM lifters works for me.

I know I'm not the first person to mention this, but too much "zinc" is a bad thing. If you take a high-zinc oil and put more in it that may -- or may not -- mix properly w/ the base oil, how are you going to know when you've passed the "Ooops..." point?

To little or to much, which would you choose. I know I just went 4 years with a .650 lift solid cam and it runs as good today as the day I put it in. Same spark plugs too. Lol.

My choice is to use an oil that doesn't need to be "improved".

Ohhhh ok. I see said the blind man. When you get that car out and about let us know how that works out for you. 😂

No problem. BTW, I switched to a solid roller, but will still run the good oil.

Forgot to ask how many miles on the street you ran up in those four years... I put about 5000 on my last .600" sft cam.

Sorry I race my cars. I haven’t been a “street hoopie” since In the early 1980’s when I grew up. My 6 cylinder Malibu does the speed limit plus a little more and I never will be a car show guy.

That's 5000 miles on a pump-gas 10-sec street car running up most of its miles driving to & from the track for both bracket races and test & tune events. No show car here, either, since I sold my A12 Road Runner years ago.

Your turn.

(We could do this until our keyboards are worn out, but I'm sure we both have more important things to deal with.)

You still win; my junk hasn't been running in 10 years. But it's getting much closer...
