My symptoms sound remarkably similar to what yours were.
"before i did the mass amount of work including plenum, i got this
start up- 50 psi
warmed up and runnin 45-50 psi
idle 35psi"
Sounds like I'm going to be replacing the plenum, I had figured that much. How difficult was the job? What did it take? Any suggestions?

VERY simple job IMO. just time consuming. take your time to clean all your parts. and the only special tool you need is a fuel line disconnect.

No prob, our magnum motors just don't respond quite like Chevy's etc they prefer the smaller valved heads unless of course you go radical then go as big as possible.
