Tony: Since your the only person that I know of that has had a 4T60 mated to a 4 cylinder, how do you think it would work with a stock (slightly modded) 2.5 as compared to a TH125? And would you stick with the 3.73 gear or change it ?
Thanks Rick------------------

Please keep in mind that I am NOT running with only 92hp. That being said, the stock TH125 has a 3.18 final drive, so the 4T60's 3.73 (33/37 gears) should "feel" pretty good off the line with a Duke.
It's almost as low as the 4.10 "performance" 4-speed manual some Duke's had. Also the OD 4th gear is about equal to the 5th gear Duke's had with the Isuzu 5-speed manual. So it appears you have almost the "best of both" - the low 1st gear of the 4.10 4-speed, and the OD 5th of the 5-speed. With this gear ratio the 4T60 shifts into 4th at about 50mph.
I also have a set of 3.33 (35/35 gears) and 2.97 (37/33 gears). I DID have the 3.33 ratio (35/35) gearing initially, but wanted more punch off the line. You also never got into 4th gear until about 60mph, so I pulled the tranny and changed the gears for the 3.73 ratio (33/37 gears).
With the tranmission swap now done, I noticed that engine RPM at 60mph in 5th gear with the Getrag 5-speed is about the same as OD 4th with the 4T60 with 15" wheels/tires.

Did I ever tell you that your car was driven by Bob Paxton at Indy during the race month? The best I can find is tha the was involved with College Basketball and I think he passed away September 2008 Rick B

They also has a tendency for water spots anytime water splashed on them.
So I got my aluminum parts chrome plated. Please excuse the glare/reflections 
Not cheap to do - but well worth it (and will look good forever).
Safastro made some vinyl letter cutouts for me to stick in the bottom of the letters.

Holy crap! Stunning.
This car should be in a magazine, with a nice article.
Seriously, you have a gorgeous beast of an Indy.[This message has been edited by FieroMonkey (edited 01-04-2010).]
