Engine, rear gear, Tourque Converter, Tire size info/question for the experts

Hey 318, recognized the name but didnt realize you were on abodies, watched some of your vids when I was timing this thing, will drive it tomorrow and get some exact MPH / RPM info.

I kick myself for not going 3:55's or with that small of a tire would that still be to much gear in yalls opinion... you should have seen it for few days I put it on the road with the 5:13's (only becasue thats whats was in the chunk when i picked it up) felt like 7k driving to the mailbox
