It even SOUNDS like a "race engine" now. Not because I'm winding it up to redline before shifting - because I'm not (always ) - but I am shifting at a slightly higher rpm than the automatic transmission would. Better control, feels faster too.
Much more FUN to drive now too!! Well worth the work to make the switch.

Got the Getrag 5-speed swap finished on on Saturday - went to Car Show NEXT day, Sunday (Sept. 27 2009) Beautiful fall day, great show. The car drove great!
Today, a week later (Oct. 4), it's cold (just above freezing) with wet snow. Summer's over!

No, there is an SD 4 cyl on there that is partially done. I emailed the owner in Bath NY. Her husband has passed and she is selling. I would like to try and get it and finish it for her. A way for her to maintain touch with him...sounds sappy but I would lke to.

I actually love yours...that is why when I saw this one so close (Bath NY) I kind of did a double take. Read my PM to you. I also looked at the engine setup, since that's the only pictures, and yours is slightly different (to me as a layman) but probably hugely different in truth. Her husband was in the process and died of cancer.

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
I had noticed it was difficult to keep a high polish on the aluminum valve cover etc. They also had 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).

And we all want dyno numbers!!!!! The 160 was way off. It should be making over 200whp I would think. if you want a good tuner, call this guy in Atlanta, Jeff @ Engineered Performance
Where can I get one of those wonderful valve covers for my duke? Heck, where do I get a super duty period? I would love to keep my car a 4 cyl... this is the most perfect build thread.

Thanks The valve covers show up on eBay once in a while.
Thanks for the info.. the car looked like the best option, just way out of my price range right now. If you ever get squirlly and want to sell that car, you should contact me.. you never know. I have been giving serious consideration to a V8 conversion until I saw your thread, I am inspired. I would love to ride in that beast some time.
I just wanted to bump this thread and say that you have an amazing Indy!! I am restoring a Indy myself currently. And yours gives me motivation, but you also set the bar to damn high. LoL
Well worth the work to make the switch.
