I,ve had everything to build a N.O.S. m715,230 tornado engine now for quite a while now and my m715 now has 57k miles on it and starting to get weak in a couple cylinders so I figure now is the time to start assembly of my replacement engine. the truck is 99% all original and I,d like to keep it this way so as they say the apple is ripe ! I have a brand new short block but I also have a N.O.S. set of civy 230 tornado pistons and there 8.5 to 1 compression as opposed to 7.5 in the military engine so I,am going to swap pistons to the higher compression for a little more torque. when i get the short block out of my storage area I,ll post some pictures of the crate and of the unpacking. they seal the dickens out of these. i had 5 of them through the years and this is the last 1 i have. alot of folk have never seen one of these being built so it should possible be of help for someone down the line. it will be 100% new air filter hsg to oil pan, fan blade to pressure plate. more to come soon.
I already replaced the transfer case and trans-pto combo with N.O.S. components. not that the originals was bad. it sure pays to keep road speeds at or lower than 45 mph.
