Haven't checked the gear ratio, but it should be o.k. It's off an 80's camero that was a v-8 and automatic. This truck is an old project I started years ago when gasoline was cheaper. If I can cruise at 60-5, I'll be happy. It will be mostly a parts chaser around town with an occational 80 mile run now and then. Let you know how it goes. Thanks,Joe.
