IMO, 4.10 is alot of gear for a DD with an auto. The desired stall you want will vary depending on what u want to do, and your combination. Based on the mods in your sig, I would probably go with 3400. However, it may be faster with a bigger converter, although that may not be very street friendly. really depends on what you feel is street friendly
i have a 4000 stall now and even with 2.73's if i did it again i'd go bigger. but, thats for my LS1. From what i have heard, the LT1's generally match well with a smaller stall than would be wanted for an ls1 with similiar mods. hope that helps
Thats because peak tq is lower in a lt1. I was agreeing to the fact that 4.10's will make a converter feel tighter. Not sure if I would run a 4000 in a bolton lt1 tho. Contact a yank or fti, they will set you up right!!
