Figured out my brake issues (had 620 cylinders), rolling again. I was wondering if anyone could tell me how much my rpm would drop at hiway speeds if I lowered my pumpkin gear to 4:11 or 3:89 from stock. I have been looking for a dogleg with no luck as I assume afew people can feel. Anyways I would like to take my truck on road trips. Stock set up I can get to 70, just really pushing the rpm.
