A friend told me about this on Crowers web site in there Q@A section, under support. Crower does Not recommend using synthetic oil for any application, they recommends a non detergent-race only petroleum based 30wt with a ZPP plus additive. I do not remember a company like Crower saying not to use synthetic oil.

I've used nothing but synthetics for well over 10 years now without a problem and my engine has a flat tappet cam in it. I can tell the difference in just the way the engine idles from synthetic to dino oil of the same viscosity. I use dino oil to clean up my engine after sitting for extended periods like a year or more and then change to synthetic. It's an instant 200 rpm increase.
From what I've heard and read on the interweb synthetic clings better than dino oil.

I've been running it for 15 years. The only time I run conventional oil is for break in. I did just switch to Brad Penn semi syn. lately. My bearings have always looked good when the motor came apart for rebuild unless there was another problem.

First couple of times I thought something was wrong with the carb or inside the engine.....till I put the synthetic in after break-in. My engine, trans and differential builders have had only compliments on how well my stuff wears with the Amsoil synthetics I've been using.

As far as synthetic engine oil clinging to parts when it sits very long(week or more) Mobil oil got sued 15 or 20 yrs. ago over the thier Mobil 1 synthetic aircraft oils causing cams to go bad in Contintental air cooled and liquid cooled aircraft engines. Mobil CO. quit making and selling that oil and payed many aircraft owners millions of dollars for new motors One of the other problems with that oil( I used it for many years and dind't have any cam problems in my Lycoming motor, my cam was located in a different location than in Contintentals ) is that Mobil 1 AV oil wouldn't keep dirt particles in suspension long enough so the oil filter could clean it out, that oil would leave and make nasty sludge deposits in the motor That airplane had ran Phillips brand aviation brand multi viscosity(SP?) oil in it for several hundred hours before I bought it, I switched it to Mobil one on the first oil change and ran it for 6 or 7 yrs, I did have one valve cover off when I first bought it and it was spotless inside, not so 6 yrs later I changed oil and filter every 50 hours or sooner I switched to Shell multi viscoty avaition oil and started running Marvel mystery oil in it to clean the sludge out, that worked eventually All multi weight oils have synthetic polymers in them to make the oil change viscoty

Just like the petroleum, all synthetics are not the same.
If the results don't match the theory, change the theory.

conventional im to cheap to change synthetic after every weekend of racing
You'll probably crap when I tell you I run mine all season without changing the oil and filter.

fascinating. i've used both synthetic and conventional with excellent results either way. mosier specified conventional in my mosier 60, but they couldn't tell me why.
My Strange S60 had a sticker on it warning against synthetic lube.
