You won't even come close to needing 5th with that combination. With 4.10's and those 26x8.5 slicks, you won't hit the rev limiter until well over 116mph and around 112 with 4.30's. I ran 4.30's with my EFI combination well past 114mph before I switched over to the AOD. Don't be afraid of gearing up...better too much gear than too little.
