Ahhh...  yer foolin with us.  A three bar MAP sensor doesn't feed
anything.  It's the huffer that it's connected to that puts the meat on
the table.

'Sides, inna big block, even the cast slugs make noise.  95 + 96 454 was
so bad, GM tech support line was telling dealers that there was definitely
a piston noise, but engineering hadn't determined a specific reason, and
there was no fix to be performed.  I know of a few engines that got
replaced due to customer complaints.
