It stiffens block to reduce flex,
No, if the block is weak in that area, you've got more problems with that engine than anyone would ever know what to do with. :-)))
Adds weight
Yes.
Gets in the way of doing any work in that area
Yes.
Paper weight
No. It's too big for the desk. Try it as a door stop.
Conversation peace
Yeah, with the insane. :-))) Milton Schick 1964 442 Cutlass[EMAIL PROTECTED]
