Measure the old thrust bearing flange if it is still in the block.

The early bearing has a 3.567" OD flange and the later is a 3.602" OD bearing flange.

For a Ford 300 six we figure 93 octane pump gas pump gas will tolerate a Dynamic compression ratio of 7.5 and still have some margin so that the ignition timing and air/fuel ratio is not so critical. If you figure setting the cam with a 2 degree advance with the intake lobe center at 106 degrees ATD...

What I'm thinking is when it comes time for turbocharging E85 will let you run without an intercooler. It's also a good fuel for naturally aspirated racing.
