The 700R has become a very popular transmission today. I always have to kinda laugh when I here that though. GM lists the 700R4 as a "Light Duty" transmission. For a performance car it is "NOT" a good choice because of the gear selections GM used in this transmision.
Ist gear in all 700R4's is 3.06 and then there is a huge jump to 2nd gear at 1.63. That is a 47% difference, compare that to a Muncie M21 4 speed, transmission were if you make the shift from 1st to "3rd" and skip second altogether that is only a 41% difference. The 700r4 was built and designed to help GM with its EPA rating. It does a good job on that front but at the cost of performance and durability.
Adam, I know this doesn't answer the questions you asked but if its not to late maybe you can reconsider your choice, and get a tranny that is more suited to performance work.
RSProtected people will never know or understand the intensity life can be lived at. To do that you must complettly and totally understand the meaning of the word "DUCK"
Dammit, another good ol boy gone. Condolence to the family. RIP Mike
