Heres one for the engine gurus Drove to ss wed 850 miles at speed.Since the build my 390 has had 40 psi at idle and 60 psi at speed. Been that way for 6k miles When i got to York I had 40 psi at idle and 70 psi at speed. Drove home and it stayed 40/70.Anybody ever had this happen? Is this a problem? Thanks

cuold be your gage is still stunned to see 60psi :shock:

My 300 will have 50 some days and 60 others. Not sure why, but as long as its not 10

I am ok with it.

Wow, FE's are known to be notorious low pressure engines. I don't think I've ever heard anyone that had it go UP! Did you add anything like STP to thicken it up at any point?
I have an old 360 that won't die and it runs at 12psi when warm at idle. But jumps to around 40-50psi at speed.
