There are so many data holes in this thread it is impossible to give You any accurate advice at all. Either You're sticking w/25" dia. rollers or not. What stall converter, what is
the rated efficiency, & where does it actually stall behind the teener? You want a drag set-up, auto-X setup, or street/road course set-up? Right-on w/the previous post about
turning the MPH You're talking, the AAR I did heads for was hittin' 109, worked out roughly 340 at the wheels, He was test shifting as high as 7200 w/that 340. It frankly seems
unlikely(but not impossible) that teener will be anywhere near that, and You stated"100-110 MPH", that's a monumental amount of HP spread Dude!! Like the diff between runs
@13.2 & 12.2 sec., where do You realistically expect to be? O/D is nice, but as has been discussed & I have warned, just because You can cruise at a 2.76-like RPM, doesn't
mean it's safe to go ahead & drive like You're running them. You can easily exceed the prop-shafts critical speed if You hit the highway & get "top happy"!!
