[QUOTE="biminiLX, post: 15903364, member: 7795"] Ford racing makes or used to make a 4.30, I ran them in my '01 Cobra. I also agree you shouldn't have a vibration issue, and if you don't plan on adding huge power, yes 4.30s would be perfect in a street/strip car. I trap about 71-7200rpm with 4.10s and a cammed 960rwhp. To optimize your combo, 4.30s would be great, better than current 3.89s. Your slicks will also grow to over 28.1" at trap rpm (guessing 140mph?) With a 2.66 first gear and 0.50 6th yes you're correct these cars respond really well to aggressive rear gears. -J [/QUOTE]
