Rebuilding 350 Olds. New bearings throughout. I see in the packaging it comes with a +10 PSI relief valve spring. Is anyone using that, or staying with standard.

 

The purple spring, yeah many of us use them.

 

 

IIRC, it's a pink spring that came optional, and the general consensus is that it's worthwhile. I'm seeing 90-100psi on cold startup with it.

 

As am I, around 90 psi.

 

Removed a few messages, try again.

 

Really, you guys are seeing that much?
My average is 75 or so cold, but it’s not as cold here as where you guys are.😉

 

Those are your clearances in my 358😏. Yeah, the warm spring and fall days here are like Florida in the dead of Winter. You can keep your Summers, I hate 85 in your temp, let alone what you get. We are expecting -25C highs this weekend, which why my car sits for 5 months of the year.
