My 71 V-code GTX is still in the original paint and has the 440 call outs, not the 440+6. I was curious also and was told that they all came this way. The 440+6 call outs were aftermarket?

Now for those wanting to get their feet wet with a 71 Road Runner project I have two available.
A factory purple car currently on the bag under parts cars and an F3 4-spd car that I don't have home, or all the details yet. oojhnoo@aol.com
