Well i got my new cam and lifters in my 56'261
gave it a 20 minute spin at 1500-2000 rpm. and just took the fist drive.
Using straight sae 30.
When i started the engine the oilpressure went straight to 45-50 psi. and 30 psi at idle.
when i returned from a 30 minute drive i noticed that my presurre with a hot engine was max 35 psi and 5-15 at idle. I am not sure if this is a problem. I also blocked of the bypass filter that was in the truck when i bought it, it did not help very much.
any advice?

Thanks,

Dennis
