Well I don't think she is worn out I jus rebuild engine and it runs way better then it did before... it was leaking oil all over the place and roasted clutch plate due to oil absorption so had to drop trans and at that point I was like might as well pull engine too and resealed entire thing put new piston rings on and few other things so she has great compression now and no oil leaks and will pull 20000lbs up hill all day jus not very fast but it has great low end power, jus when I get on the highway I become the parade leader cuz " I can't drive, 55" haha..... I thought 2 speeds you could basically have my ratio now as the low end side and then have high end side ratio for once you get the ball rolling good you can keep it rolling good(highway speed) but if I'm wrong about that plz sumone inform me why and possibly how to accomplish more speed without losing low end power
