I've noticed on my stoker motor that it seems to have more power when the oil is cool. The reason I'm thinking this is because at startup when the engine is cool it has great power...once the engine is warm i.e. in about 10 minutes, it still has great power but at this time the oil pressure is still high leading me to believe the oil hasn't yet warmed up completely. Once the oil pressure comes down after driving about 15 minutes the engine doesn't feel as strong.
I'm running Mopar performance valve springs with a comp cam 68-231-4 and stock issue lifters.
My oil pressure at startup is 50 psi at idle and about 75 over 2000 rpm.
Fully warmed up my oil pressure is 20-23 at idle and approx 50-55 over 2000 rpm.
I'm currently running a 10W40 oil dino.
The engine has 6k miles on it but has had this problem the entire time.
Is it possible that the stock lifters can't handle the valve springs once the oil warms up and becomes thinner?
