that hswap of a friend of yours looks clean as fkuc btw. pretty bad ***. my only problem with the motor is that it weighs a ridiculous amount for the power produced. other than that their cast iron sleeves are probably their biggest selling point in my book. they can take a fkuc load of boost without blowing a sleeve. that is the biggest downfall with the bseries. aluminum sleeves loose their integrity around 20 psi boost (depending) so the b-block is only good to about 500 whp without sleeving it. but then once you have a sleeved b-block on your hands, it's just about how good of a turbo setup you have to put down 500, 600, 700, 800,900++++ whp. just my .02 on swaps.
