thanks estout81 and Fordestes now I am totally confused, I have a 239 over .060
my rpm will b 2000 at 55 mph, I am looking at Speedway for the parts, is that the right place?
my 49 F1 is 3:92.1, and I'm thinking of changing to 3:08.1
the transmission is heavy duty 3 speed on the floor
has any one done that and with good results?
it is an 8BA built by Walt
I am kind of new at this, but here goes
my 49 Fi really revs up at 55 mph, and the ratio is 4: 27
what is the best solution to drive at 65 and reduce rpms
I finally drove my F1 and thanks to all the informative posts from everyone especially Walt who rebuilt the 8BA it has been a fun project to use most of my spare time
on my 37 rear end there the numbers stamped where I understand the gear ratios would be and it is 1 39 and a inch or two away is stamped 2 and that is all how can you tell the ratio from this?
