Tim,

Great little video, is that Moss Motors that specializes in English sports cars?  I just ordered 10 bottles of additive from CompCams.

Funny that you bring this topic up, I just pulled the cam out of my 312 that had a disagreement with the nitrous at the starting line at last years shootout. I found that the number four cylinder has a intake cam lobe that measures .171 shorter then a good cam lobe and another lobe that read .075 shorter. The first thing that I thought of was that I just started using Valvoline racing oil so I checked a bottle and it says that it has ZDDP in it. I have always been a Penzoil man till last year I switched to Valvoline because I cannot find straight weight Penzoil around here anymore. I use 20W50 in my trucks and if I remember right in a fit of haste I used it the 312 one time, that probably was my cams fatal blow. The good news is that I get to maybe try a different cam grind. The ISKY F-300 is the grind that I have had in the car since 1965 and I am thinking that it's time for a little more mid-range. Has anyone had any experience with the Isky RPM-300 and also the Isky F-300. The duration is 270 in the RPM-300 and 286 degrees in the F-300 and they both have the same lift. I'd hate to loose the low end torque but I think it won't be too noticeable.

that ZDDPlus is way too expensive

So is medical insurance...

Rather simplistic, and there are other options Diesel oil for one (even with the new reduced formula there is plenty of ZDDP for a Y) How long this will be I don't know.



Supposedly, any oil rated SM should not be used in a flat tappet engine. I have heard that any oil 30 weight and over still had the required ZDDP, but check the rating.



I checked Castrol 20-50 the other day and it had the SM rating. I use the diesel in my two Y's, will switch to that in my non-roller 302.

Guys, what is the risk, if any, of TOO MUCH ZDDP?  For example, Ive been running diesel oil (rotella T), but if i added some ZDDP plus (per recommendations), would it hurt anything?

I don't know how much would be too much, but I think (and hope because I do the same thing) that adding a bottle to Rotella is not a problem.
