First off I'm going to assume it is a 2 piece seal engine with the perimeter bolt valve covers......they are all the same basic engine but with different cams. I don't know how you would know what cam you have unless you pull it out. My crew cab I just bought has the 250HP 10067353 crate engine (luckily the PO kept the receipt for the engine)

then there is the 290HP 12499529

and a 300HP 10067353

if you notice in the specs they all have the same basic specs (block, heads, ect), but with different cams.
can you tell I have recently been researching this for my engine
