hey guys. im looking into building the 9" i have in my 77 f150. though i shelled out my trans the other night, turns out after going back and looking playing around with it, i lost something in my rear axle.
my question about building a 9" is should i go 31 spline or 35 spline with good yukon or moser axles. i run 285/75/16" and don't plan on going any wider or taller. i want it to able to handle 550ft lb and 450hp, dont plan on building my 429 past that. im plan on using a trutrac diff and 3:50 gears. i use this truck to do some towing in the 5,000 to 7,000lb range, and for fun driving and occasional street racing. i dont off road in this truck, but i does see some mountain roads. truck with me and a full tank come in at 4900lbs
any insight how well either one would stand up to my usage would be great. i sure dont want to have to build a rear end for long time given the prices.
