Will my 360 cast crank, cast piston……

Yes, the goat pee they pass for gasoline out here is pretty bad and was thinking if I kept the boost under 6-8lb range, I could get away with it. I am thinking it might even be better to put the assembly on a 5.9 magnum crate motor as not to have to worry about the cheap parts. Sadly, with the guy doing my work pulling the rug out from under me and tripling my restoration, correction repair on my project and not having a garage to work on anymore means this unit either goes away or shelved til I figure my finances.
