i beleive i figured the gear ratio once to be either a 3.23 or 3.21 and with a 904 so it might work fine i will have to get it through a safety check so i might change the tires to some 235's to avoid the hassle they might give me with the 31"s
so either way i'm going to kill my low end torque i was hoping to get low 17's to mid 16's out of this old truck wich i was thinking i might be close to but it looks like that might be out with the tires i was looking to run then again i was thinking of having 3 sets of rims and tires for it
Dang, I need to get a job with you if you can afford 3 sets of wheels for 1 truck! lol
I actually had 31's on my old '84 shortbed w/ a Super Six in it and a 904 trans and 3.21 open diff. Didn't seem to kill the low end much at all, I could easily spin pulling out of anywhere. Taking off in a straight line, it would just spin a little. Low end torque is the S6's trademark anyway. Also, I hauled plenty of heavy loads on it with those tires, never had no problem pulling, I always shifted it manually though.
