What rear differential gear do you recommend for the 4.6L?

4.30's are an awesome gear, i was gonna go 4.56 in the 99 cobra and all hell would of broke loose, lol. i am thinking of going 4.30's if i dont do a blower swap, my cars not my dd any way. awesome thing about 4.30's in our cars is that you dont have to down shift and just wind the gear out, right el presidente

If I change mine it will be to 4:30 or 4:56... you need them for 1/8th mile tracks. I dont fly down highway anyway
