Another flat tappet oil

Very Interesting....Castrol Edge 5/50 synthetic, do you know the PPM's for the zinc and phosphorous by chance ? Is your 468 BBC a Flat hyd or solid, EDM's or other lifter mods to help the lobes & lifter faces live? I like the 5/50 numbers.

 

Its a hydraulic flat.Nothing special.Im not sure on the PPM numbers.I only know about the oil because I had contacted Castrol to see if they had a full syn oil I didnt have to add the zinc package too,which I didnt mind,just looking for simpler.My 468 likes 10-40 the best,and he said this was same as that,with the zinc in it.You could email them on it I guess,and they would tell you.IDKW that info is impossible to find on certain things.

 

Isn't that a 2013 report ?

 

Thanks for the info krabben1, much appreciated. always nice to have options...and it's a syn. to boot.

Thanks for posting the link, I will be looking into this further for sure.

 

Here's something most people need to read.

Looks like I'm good to over 8000 rpm. Have to run it down a mineshaft to get it there though. Interesting info on bearing clearances too.

 

I was helping a buddy at the race track one weekend several year back. I told him to plug in his oil heater on Sunday morning (warped around his dry sump tank). He decided to drive his car around the pit area thinking he got enough heat into it. He tore up the bearings 1st pass out. This large small block made just over 1000hp NA. This 63 corvette was running 7.70s the day before.
