What is the normal RPM in 5TH gear @60 with the TT rearend?What is your rpm at in fifth gear going 60? with 410/na rear end? I have just finished my swap and it seems like fifth gear rpms are high at highway speeds. I have noticed only a 500 rpm difference between fourth gear @ 60mph and fifth gear @ 60mph. I kinda thought the rpms would drop more. Maybe its just me since I have finally driven my car after 3 years of rebuilding.
