Later this month I am picking up a 76 Bronco and putting my axles and lift under it along with my 5.0 . The 76 has a rebuilt c4 with approx. 20k on it. My axle gears are 4.88 and I have 38*12.5's. Am i going to hate this set up, are 4.88 enough? Also should i put a different torque converter in it while it is apart? My 302 has around 5k on a mild cam... anyone with similar specks? I'd appreciate any info. Thanks

I run 37's with a c4 and 4.88 gears. I wouldn't want to go any lower unless I had overdrive or never drove down the highway. I now have a doubler but had no problems with just the d20 when crawling. I would keep the stock converter.Originally posted by beatupbronco View Post69, 342 EFI, C4, NP203, D20, 4.5" SL, 2" BL, 4.88 9" 35 spline ARB, 4.88 HP D44, WAH, ARB, CTM's, front disc , 37 x 14.50 Toyo MT, Ram Assist, and rear 4-link -
4.88's are good with 38's. 5.13 IMO work better, buts it not worth the 500$ to swap over.Mark Harris

That's good to know. This bronco won't ever see the more than 60 mph. I just didn't want it to be a slug while up in the hills or in the snow.Comment
