JM7.3CW Eh!
Im not sure if you were thinking out loud or what, but that was basically Justin andersons build.
He also had his stage 1 cam in it and shaved 94-97 powerstroke rods shaved down and balanced as an assembly. 21 pounds of bob weights to balance.
Justin blew some prototype decompression headgaskets on his bronco. He is now o-ringing them and using stock headgaskets and compression. He is planning compounds and 50+ psi. He blew his intake collector at 56 psi before the headgaskets went later on down the road. He will also be putting a stage 2 cam in it the next go around.
I would agree with what several people have said, filling the block is not necessary. I would do a bottom end girdle and studs and cam. You wont need more than that to run 15-20 psi. Heck head studs you would be fine for that.
If I were doing an engine build I would do much the same
cam, studs, girdle, ceramic coat pistons, total seal second rings, ceramic coat all exhaust piping to turbo and down pipe. I don't think I would do psd rods just because idi rods bend around the 400 hp mark. I would also want the roller rockers on just because why not. At that point you would have an engine that would hold together and could do whatever you wanted with it. then just fuel and air.
