Sounds like your rear end has a 3.36 ratio,Dan. GM didn't offer a 3.25 ratio from 1955-64,,still don't.

I took note of the engine RPM's at that speed... then did the same at 70...   doing the math... 2900RPM @ 60MPH=3.27 gear ratio and 3350RPM @ 70MPH =3.25 gear ratio   So, I believe I have a 3.23, per the list from Tom... (thanks tom)   What do you guys think about that RPM?? Is it too much?   Thanks again for all the help!!     Dan McIntosh Pavement Scraping 1964 Impala SS http://www.lowriderimpala.com       ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, July 22, 2003 7:04 PM Subject: Re: [Chevelle-list] rear axle ratio??
