i'm calling shenanigans on that 650hp 406 for 6.7. you'd need nearly half that in heads alone to put down that kinda juice.
yeah, maybe he got some deals but two things: one, how long are those questionable parts gonna hang out-- especially if he cheaped out somewhere on something; and B- the machine work costs what the machine work costs. unless you have some back room deal, that's at least 2K in machine work: converting to aftermarket 4 bolt mains, align hone, deck, blah blah blah and then throw all the ARP **** at it.
post up the receipts oscar meyer or get to steppin'
