Okay.. real quick question, do you have the cam card do you know where the intake closes? 10.4 and that cam..that on the description says 9.5 or less compression has me wanting to check the dynamic/cranking compression.
you really don't want a gasoline engine puller or tow type truck cranking 200 PSI per cylinder 'hypothetically speaking' without some octane cushion. 91 octane isn't enough.
you'd be better off to get a diesel if you need that whereas the connecting rods can handle it and everything's built around it and you can just throw diesel swill and make all the torque you want. Just my thoughts.

Just for perusal;
Several guys on FABO, myself included are running, or have run, near or at 200psi with aluminum heads.
I have never run anything but 87E10 at 930ft elevation, and a minimum cooling system temperature of 205*F. My engine was built in year 1999, and has over 100,000 miles on it. The Scr has been as high as 11.3 with a 292/292/108 Mopar cam. and as low as 10.7 with a 223*.050 Hughes cam. Currently running 10.95 with a Hughes 230* cam. I run a A833 and 3.55s at 3650 pounds. Goes like a scalded leopard.
