Hey guys, that time of year where all I can think about is squeezing every little ounce of performance out of my 71 Duster. I have been thinking about trying some q16 fuel. From what I have read, the more air starved your combination is, the bigger return you will get from it. My motor is probably about as air starved combo you can come up with. I am looking for tips, tricks, etc. to get the most out of the switch. Currently I am running c16 which is probably overkill for the motor (all cast iron, 13.5 comp), but the cranking compression is around 250psi so I just want to be safe. I realize I have to jet up, but read conflicting information on how much to start with. What is the target a/f? Same as normal gas?
What about timing? Does it HAVE to be dropped? My motor likes pretty low timing but getting it so low kills bottom end tq (may put on a programmable box).
Sorry for the long post.

Thanks guys
