Economy axle.  As if.  Good guess, John.

Hello John,

 

Here’s the link to an article by our friend Burt Bouwkamp, archived in Allpar.com. Scrolling down to the 1960 Speed Weeks section, you’ll see Burt’s recollection that Gregg Ziegler was running a 2.93 rear end.

Hi ,
Anyone know what the axle ratio was on the 400 hp F’s that ran almost 150 at Daytona ( or G) ? Axle ratio would have been very crucial to that attempt , and ?7 F cars ran .
From memory a stock ratio F axle reads about 2800 at 60 mph , so 120 at 5600 . That is pretty much it on a b block ; however stock tach and speedo not exactly precision things .
They must have had like 2:90 :1 or something, maybe 2.70 ? Assuming 150 mph happened near hp peak rpm on short long ram . Which is not that high in rpm —
Related , and easy if anyone has one out , I need to find out the exact dimension , brake drum wheel face surface to surface across an f or G axle , and exact distance c to c across spring perches . Hard when in the car ...
Thanks in advance for any comments ,
John G
