Drilling oil galleries and oil return holes?

Don't forget to give the rear main cap some help at the sharp corner, and get rid of the 90* adapter.
With these mods,and some others, my 367 has been running up to 7000/7200 regularly, since 1999. The last time I did a refresh was 2004. The used bearings went back in, and now have over 100,000miles on them.

I'll go have a look at the rear main cap. I'm guessing you mean soften the corner a bit with a die grinder?

As for the 90* adapter I believe my exhaust requires it. I couldn't make an oil filter screw on without the adapter. Is there something I don't know here?

Thanks,

CE
