<VV> 65 Monza 110hp engine question

[Matt Nall]

The spark plugs were Autolite 425s that are only 1/2" reach, so I 
changed them to Autolite 65s with the correct 3/4" reach and ... the 
engine immediately had a knock.   Removed the plugs and sure enough #6 
and #1 had the ground electrode hit by the piston top.   A couple of 
others had the piston top kiss the cylindrical end part of the spark plug.

Larry!!  you've been working on that 455 Olds too long!


425's / 1/2"  is correct....   INLINE  230/250/292  use the 3/4 inch..
