340 Truck Engine?

[TimCounts]

I've gotten into a bit of a restoration project with my father.  It's a 70 cuda that was originally a slant six but I've purchased a rolling chassis and intend on making it worth having.  (it has several issues that I will be correcting, front fenders and bumpers being from the wrong year for starters)

 I've found a '69 Dodge D100 that has a 340 4 barrel engine that I would like to put into this car.  Was there any difference in the engines they put into the trucks from the cars?

Any insight would be greatly appreciated.

Thanks,
Tim

If it helps, here are the block numbers the seller has provided.

drivers side = 2780930-340-6,  passenger side = 9B340336, stamped 12.9.68

Thanks,

so it is a 69 340 steel crank high compression 340 which should be an awesome engine assuming it is relatively stock still , if it has been rebuilt who knows what was done .
 No 340 was ever used in trucks due to a lack of torque so this engine was installed in a car from the factory originally & transplanted into the truck , oddly the engine & truck year do line up though . The engine did originate from the Hamtramk plant
 you will need a different K frame or mounts to put the engine into the cuda otherwise with the right mounts it will bolt in.

Thanks for the information, that is great news. 

I already purchased a new k member in anticipation of a putting in a v8.

Cool , do some welding & bracing on the K frame before installing .
 the same K frame will accept a LA , B or RB engine
