Turbo 360

Have a question for some input. I just acquired a few fully balanced rotating assemblies from a friend of mine. I plan to use one set in a turbo 360 I'm building for my dad. Mild Turbo build 360 using open chamber edelbrock heads with a non-decked block so roughly 9.5:1 CR, a custom .470-.470, 232/232 @ .050 on 110 LSA solid flat tappet cam from Racer Brown and either a 500 cfm edelbrock afb or 750 AVS customized for blowthrough on top of a Torker 2 intake. The turbo is a On3 T4 88mm my friend gave me. My question is do you think the Eagle SIR rods that are in the rotating assemblies will hold on anywhere from 6 to 10 psi of boost since they are I beams made of the 5140 steel instead of the 4340? Rough goal is like 600 horsepower.
