How much horsepower can a Saginaw 4 Speed handle?
· Herein, is a Saginaw 4 speed any good? Only good thing about them is they are very easy to rebuild, you only need a brass drift pin and a good pair of spring clip pliers. I have used more Saginaw 4 speed transmissions than I can count. They will hold up with no problem if you want to drive cross country. Subsequently, question is, how much HP can a Muncie m22 .
