Slant 6 turbocharging- yea or nay?

"as for roller cams Schneider ma in S.D., CAkes them and 440 rollers lifters drop in"

Can you translate this into something I can actually read, please?

What is "Schneider ma" and do they have anything to do with the long established Schneider cam company that uses a Maltese Cross as a trademark?
What 440 roller lifters are you talking about? Are there OEM roller 440 lifters, and are they different from the 318/360 Magnum roller lifters?

Any contact information for the Schneider roller cam company?

Thanks loads for any information!!!
