Im biulding a 383 with a forged rotating assembly. I plan on spraying a 200 shot also. I need to know what length rod would be best for this app. I would like to use 6in but have heard 5.7 would be better for a nitrous app. Should I just shoot for the middle and get 5.85 .

I also plan on using SRP flatop pistons so it looks like my compression is going to be about 11:1.....should I use gapless rings?
