sorry about that. my home track will probably only let me run 1/8 to 1000 foot. but when i go to monster mopar or nor walk which are 1/4. i was wondering if the 4.56 would be to much gear for me. the 10 inch was for the other 440 i had in the dart that i never got to use and is going to have to do for now. Dewayne said to get a 5200 stall converter. which i plan to do but just not right now.i might just stay with the 4.10 but i wanted to see what you guys would say that are a lot smarter than me.thanks mopar65
