what kind of rpm drops could I expect if I change the rearend gears from a 410 to a 373 or a 355? I use truck to pull a 13xxx LB 5er! Would 355 gears be too much ? it is a 2000 7.3 auto stock as of now planning to add a flip chip to it.
Wife just called daughters boyfriend was using my Ex to tow one of my trailers to move into his new house. while backing trailer up driveway he said temp spiked to 215* and dumped fluid in driveway, hoping its just a line.
