[QUOTE="highrolrcustoms, post: 409061, member: 3527"] So im currently running a Np203/dana 300 doubler. Works great for crawling but feel im lacking in strenght with the 300, ground clearance with the 203, and length of the combo. If i read right the np203 has a low of 2.0:1 and the 300 has a low range of 2.42:1. So when im in double low my final ratio is 4.42:1. Correct? I wanna go ahead and swap over to an atlas but not sure if i have enough motor for a 3:1 case. Plans are to have about 400hp by next season. I really like the crawl ratio of the doubler but affraid if i go with a 4.3:1 atlas it will hold me back when i need alot of wheel speed on hill climbs and things. Currently running a v8, turbo 350 tranny, 1 tons with 456 gears and 42,s. Once 42s are worn out i will be moving to 43" stickys. So which atlas do i buy? Or even look at a atlas 4 speed to.give me more options? [/QUOTE]
