Would a 305 in a 81 Jimmy be a lot less powerful than a 350? Also, are the manuals more reliable than the autos? I'm going to go look at an 81 Jimmy tomorrow that has a 305 and stick. I like my stick in my Civic, it's fun, but i've only test drove a K5 with a bad clutch and it wasn't fun at all. I'll see how this one is tomorrow.
