Re: Overdrive transmission for our big blocks

[Joey <jake4@xxxxxxxxxx>]

Hi Bill,
Look for the 518's in trucks or vans, real easy to spot, the pan shape is 
the same as a 727 but deeper so you get a good pan from the start. Our 65 
Coronets do have a larger trans tunnel than the early A-body but the rear of 
the trans where the OD sits might need some floor massaging. maybe those GM 
transmissions that Keisler sells are more compact, I really don't know.  It 
killed me to make the opening in the floor for the Jerico.
