Anyone know of a good engine mechanic/re-builder with a lot of experience on old V-8 engines in the Arkansas area or bordering states?

I bought the truck in April and as I might be moving to WA this winter (and might have to drive her all the way) Feel like I should have someone knowledgeable check out the engine as I haven't had a classic specialist look it yet.

Any suggestions help would be much appreciated. Thanks.
