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

My 914/6 3.0 conversion is custom geared A, F, O, X, HB (flipped).
I can easily use it as a 4 speed for jack rabbit starts, but having the granny gear 1st comes in very handy for stop and go traffic, line ups, starting on grades, parking, etc. The flipped HB is one tooth shorter than the H that V8 guys use, following the aircooled 3K rpm rule and stock height tires I can only use it at 90 mph and over. For street use with an aircooled engine would make an H gear all but useless. |
