Nope, I had a Craftsman 7/16" combination wrench dipped in 90W140 I teethed

We just started the engine.....all the extra parts sounds GREAT!
And you no doubt already know that one of the problems with EFI is it
smooths out cam lop and improves driveability.....so honestly even a
550HP
Cleveland stroker like mine sounds tame with EFI...the nuts and bolts
just
kinna jump around inside the 8 throttle bodies, make a lot of noise and
make
everyone think you really have 750 HP.

Dick Drenske and I may have dropped about a 100 stainless steel screws
and
washers inside the 8 open throttle bodies.
Could this harm the engine?
