    3.55 are better since you don't have an overdrive trans. Highway cruising rpm may still be a little high but not as bad as the 3.73.

    Welcome aboard.

    I have 3.55's and I have a 347 with a C-4. I think you will find it a better gear for highway cruisin'.

    I see you are from Michigan. You are in luck. The Maverick Comet Club International, Inc. (MCCI) will be holding their 19th Annual Roundup Nationals in Dearborn, Michigan this July 24-29. You will see lots and lots of Mavericks and Comets. You will have to plan and attend. More details can be found at www.MaverickCometClub.org

    OK, you lost me here. You say stall speed can't exceed cruise RPM but you say not to chance the 3.73's. Seems to me the 3.73's would help keep the cruise RPM closer to or above the stall speed. I ran a TCI 10" in my TH400 that would flash to 4200 when I launched and with more street time than track time the trans lived a long healthy life. Just trying to understand the logic.
