Chevy also made a 3:31. not that you would find one. And there is nothing realy wrong with the glide.I ran it for years on the street with 3:08s @ 16-18pmg.(With a Highly Built 250 and it ran 15s with 3:08 gear & a glide) But a lower first gear would be better yes, be it a AT 350 or a stick 3-4 speed.
