So i have a 1991 gmc sierra 1500 with a stock small block 350 and it has the hm290 manual transmission i rebuilt 2 weeks ago
So im plannin on putting a little more hp on the engine about 300 to 400 hp but i wanted to keep it manual but I heard these transmissions are wimpy
My question is it possible to upgrade this transmission? Or should i swap it out for another stronger manual transmission? If so what are some good manual transmissions out there that would directly fit ?
