Gus,
In keeping with the true bolt in deal. In other words being open and up front as far as costs go, the transmission will include a shifter and linkage. If we didn't do that, we wouldn't be any better than the "other" guys out there because you would need another $400+ dollars worth of shifter and linkage to be able to use the trans. It will be a HURST style shifter. Long makes good stuff, but it just isn't gonna fit where it needs to.

A note to everyone. Making a .85 OD ratio in my opinion is a waste of time. Our current OD Hemi 4 speed gearset has a .80 and I have heard people saying that it isn't enough overdrive. So, I can tell you that is out. I am on the fence about making a 3.2 first gear. That is PRETTY steep. If we make a steeper 1st gear, I am thinking something in the 2.9's.

As for Quadrini, I'll never tell.
Thanks,
Jamie




the .8 of the 4 speed isn't steep enough only because first isn't steep enough

check out the A580 tranny ratios in the LX's....mid 3.59 for first, and IIRC, a .83 OD, coupled with a 2.82 rear, has the same gear multiplication as a 2.64 first and 3.83 rear, and the final drive of a 3.54 with a .66 OD.....to me, the big thing is this strategy keeps the driveshaft RPM down. for instance, for a 27" tall tire at 120 MPH, that's 1495 RPM at the wheel. using a 4.10 gear and .66 OD make the driveshaft RPM 6130 RPM, with the engine at 4050 RPM. a deep first/1:1 OD with a 2.71 rear has both the driveshaft and engine spinning 4050 RPM at the same speed....

the crown victoria police interceptors are actually electronically limited to 125 MPH because of driveshaft RPM....
