Dave,
It's going to be a while. It's far too cold out here in the Midwest to try working on the truck. I'm just trying to figure out where I'm going, before I start the journey.
This banter on the gearing on my truck is bringing many valid points to light, but it is really secondary to the engine. If I don't know what I got, this truck won't move, rendering the top speed a moot point.
The engine is most likely a SBC 350 or 400, and apparently the harmonic balancer is larger on the 400. Does any one have pictures to compare the two? All that Google images is giving me are stock photos.
