it might but would you really get much more power? bigger engines dont rev as high and dont nessasarily have more power. it would definatly have more power then the stock .15 but maybe a good .15 or .18 would be better. it will also be bigger and weigh more than a .15. i would check the hp and rpm limit of the engine, plus the mounting dementions of the engine. make sure it would fit first, it should. would the truck hold up to it? you might have to replace cvd's, gears, ect.
