Purchased 7.3 liter long block arrive when he said it would the price that they said it would came with all the gaskets that they said it would came with all the OEM parts upgraded crankshaft dealership that is installing it said it was put the together with the right parts to and the dealership never even heard of this company because we're in Texas and they were up north haven't started it yet so I might change my review but it doesn't look like it. Looks like as advertised.
