I've never heard of a long tailshaft 904. As far as I know, they're all 31" OAL. 727s, however, are 35" overall. '65 Belvedere? I'll bet you've got a 727, that's what mine came with.
Wow, not quite what I was expecting. I was actually hoping for a 9:04 because they draw a little less power. But at least a 727 would be a little more bulletproof right? I'll take a picture of the numbers tomorrow after work and post them up.
