Good running truck, have no complaints for what I use it for.  I got truck in a trade with other items.  It has a Z24  banger with 2 plugs per cylinder, 5 speed, and front disc brakes.

I just use it in the back yard to haul parts and motors around when needed.  Possibly in the future it would make a great frame swap for a 521 ot 620 truck.  Its been done before and is simpler than you think. 

The 720 truck is good, the carbs are crap cause of all the vacuum lines and the engine cannot overheat once or it will blow the head gasket soon after that.
