You guys think if I go 4.30 or 4.56 be to much of a gear?
I was thinking at least a 4.10 after doing some readying. Read that if it was a cobra be at 4.30 for high rev fun but not sure what be best for the sohc motor without hurting it to much on performance.

Stick with 4.10 & your correct about 4V for 4.30 gears. If you plan boosting down the road id get 3.73 or 3.90 gears.
4.10 or lower. If u don't do a ton of highway get the 4.56
Yeah no boost for this one. Just want it to be a fun all motor car. Used to drive it all time but now mostly is parked. But I'm leaning towards 4.10 since seem to be the ones most people recommend.
If its a daily driver, do 3.73's so you don't take a huge hit on mpg. If its a weekend car and won't have boost or built motor etc... just a fun street weekend car, then do 4.10's for sure.
The mpg difference between these two gears is not what everyone tries to make it out to be, if you're changing the ring and pinion gas mileage shouldn't be on your list anyways.
Yeah no biggy on the mpg, it's a v8 regardless is going waste gas, when I put the cams I knew it was going to waste more anyways, would a 50 shot of nos be noticeable in this cars? Is it worth it, 130k in clock wondering if the good old motor can handle the extra work.
I know that's why I was leaning toward 4.10S
Thanks
Weekend car now, was dd until I got my Chevy slave 1500 for the dirty work. Maybe I build the motor if it goes out but currently doing a cobra swap so I hope not any time soon
I lost 3 mpg on my car from 3.27's to 3.73's and that sucks. Used to go 300miles on the highway on a tank and now not so much. Its something to think about. Since its not a DD then go ahead and gear the shit out of it. I also wanted more then 115mph out of 4th gear so I went 3.73 over 4.10s.
