I have a 74-914 with a 4 cyl Raby engine 2270cc. It has the 901 side shift trans. Tired of the dog bone pattern. What would it cost to go to a 4 speed, 1st to 2nd position and make the smaller gear integral with the main shaft and possibly replace 4th gear with a lower highway ratio gear for mileage. I know this is common with V8 conversions etc. What is your thoughts. Thanks

Thanks You have to remember that the T4 doesn't like to be lugged and you have run about 3000 rpm + to get proper cooling from the fan. With a performance T4 engine on the street you have to keep this in mind because you will be tempted to run at 2k to 2800rpm. The oil temps will look good but even the slightest incline will send head temps soaring if you're lugging the engine. V8 engines are WC and can handle low rpm cruising. |
