Manual trans only?

April 1968 issue of Car Life tested a 68 Chevelle 327/275 powerglide, just an ordinary grocery getter, so I cant see how NHRA would not allow it. I have three 327/275 road tests in my database, all three are auto trans.


Those NHRA Excel sheets are not error free for sure, they have both typos, cut&paste errors on the weights, and just plain history errors. Maybe bring it to their attention and they will change it or defend it!


OOPS once again I was typing too late at night, I had 275hp in my tired eyes instead of 325hp. All the road tests I have on the L79 are 4speed only, nothing I can add there. So unless Chevy submitted some specific documents to NHRA that said "also offered with automatic" as Ford apparently did with the 66-67 Fairlane/Comet, I can see why NHRA would not allow it.
