Which kind of 390 are you talking about? A stroked 351 (a 393 to be exact) or an old FE 390?

lol,
yeah, I think he's talking about gears, I was thinking about a stroked 351w at first too, that makes two of us :)

To answer the question,
I say since you have a 5spd, your 3.73s will be enough. I wouldn't put more than 3.73s on a GT (2v) b/c they have enough low end (Cobras need 4.10s or 4.30s, some even run 4.56s :) )

I can rev my motor much higher than a stock 302 so I decided to go with 3.90 gears. 4.10s seemed a little too much gear for my engine, so I backed it down one step. They have been great so far!

They are so close anyway I don't think it will really make any world of difference. anything is an improvement over stock 2.73s if thats what you're running now.

Get which ever one is cheaper.
