I ran across some old letters this morning digging through my 40 yrs. old FB records. Both are from Pontiac with the older responding to my questioning how to order a '67 GTO w/o sound deadening. The other is a response to my questioning the use of the higher ratio rocker arms w/ regard to push rod length. I wanted to share them with those of you who would enjoy them, but wasn't sure of where to post them.
