 Cavebear, is that the one you used or is that one an extra deep sump you have ?

I put one on the turbo motor shown in my avatar. Never any oil pressure problems.

Got the same one.

It's new old stock. I considered selling it, but decided to use it on another
turbo build.
Feeling it's texture, would this have been sandcast?

Probably, pretty pricey to diecast in runs of only a few hundred pieces,, probably done 50 at a time..

Yes, Bill Bowman had them sandcast. I ordered mine from the International Four Owners Association, of which he was a member.

The advantage was (in the 70's) another quart or so of oil and I never experienced a low oil pressure incident - being one of the few back then who actually ran an oil pressure gauge. I also ran a Ron Black car oil filter conversion (the first one) and was shocked at how much longer my oil stayed yellow as opposed to black to gray.

The drawback was that Bill didn't see the popularity of 4 into 1 pipes, and most of them weren't designed at all, much less designed to accommodate the Bowman pan. A Bassani will, though. And it was the best pipe anyway...
