86ford

I was looking for that chart for a buddy of mine. Good info right there.

Saromero

I had 4.56 installed and was disappointed a bit cause I was expecting a noticeable difference in more power than stock. Gas was a big improvement. 4.10 would be a waste of money to me. You'll get more power with a cai.
The edge evo made a big difference on mine an corrected speedometer.
