Ray, I thought about it more after we talked the other day...having OD would be really nice, but there's no way it's worth 3 tenths to me. Not even 2 tenths. I'd go w/ the 727 every time if I knew it was even 2 tenths quicker. Especially considering the cost. I worked long and hard to get my car to run where I'm happy w/ it...it wasn't built for fuel mileage, lol.



that's why I called you. You know whats really important





Why not just go with a Gear Vendors.????



Chris..



i may, just wish the GV was .70-.75.




For what your doing i'd still take the 4L80E over a gear vendors. Call me and we'll talk about it. I've done both. I don't believe the .2-.3 loss in E.T. from what i've seen. I think sometimes people mismatch their tire and gears when they do the changeover.
As far as A/C, I can tell you the Vintage air unit is superior to the classic auto air system. I've installed both and the quality of the components is far different between the two. We've had to do numerous warranty repairs on the latter but not a single one on the Vintage units.
