yeah that tranny isnt going to hold up especially with that high gearing. are you sure it isnt a 5 speed? maybe they just took out 2 gears because they exploded lol. iv done that before. a 5hp briggs with a torque converter will move it along just fine. youre going to have to regear it for sure. thats a crazy setup. youll have to flip that diff around to get the sprocket on the right side. but looks like thats the least of youre problems right now
