  1. Typically an rd690"S" would be 44k rear camelback. An "SX" would be 58k or higher. "ST" would be either 34k or usually 38k. If this was a concrete mixer then yes I expect it's just a solid beam version of the Mack Camelback.

  2. Great trucks; you're going to want to fix this intake tube though, keep rain from getting in and ruining a nice truck. Also its letting unfiltered air in.  This radiator has the reservoir in the top, you should just barely be able to touch it with your fingers.  You can spot coolant leaks by looking for salt trails, common leak spots are the freeze plugs on the driver side, as well as the crossover hose (very short) between the front and rear head water manifolds, also on the driver side.

    Does seem strange that the oil is only on one side of the dipstick. Next time check the oil before starting the engine.  I have an E7 that if I check it 5 minutes after shutting off it'll be a gallon low on oil, but if I check it first thing in the AM it's full.

    Yes, I have. They are super low cost! Is that what you guys here are using nowadays? My thought process is I can't afford to be cheap because it costs more typically.

    My Mack dealer uses PAI parts for engines frequently.

  4. I don't see any reason why the engine wouldn't fit in your truck and work, assuming they're both ETECH or ASET AI engines.  Might be minor differences on ambient air temperature sensors, but you can probably swap computers and make the 460 think it's the 300.  Once again assuming the 460 is an ETECH.  Turbo and injectors and a few other mechanical parts may be different.

  5. What year is the E7? Would help to know if it's an eup engine. What chassis is the donor engine from and what chassis needs it? Different chassis use different bulkhead connectors for mating the wiring between the engine and vehicle harnesses.

    There's a very thorough writeup on here regarding the AI delete. Cam, exhaust manifold, turbo/exhaust pipe, etc.

    What transmission is in the truck right now? You need to make sure the trans can take the extra power.  Also a 300hp drive shaft is weaker than a 460 driveshaft.

  6. "It was made in Pleasant Corners, Near New Tripoli, PA. Under the paint you can just make out "Sand Springs Roller Mill." I bartered for it from John Greenall. I forget the name of his farm. He was a participant with us in the Liberty Bell Trek in 1976. It is as close as I could find to what was probably used by Hartzel's between 1860 and 1930." - from my Dad. 

    Our business has been around since 1860, used to be lumber yard and a feed mill. This wagon is definitely not fiberglass, it's very much made of wood. Wheels, spokes, hubs... All wood.
