Honestly i would never trust an engine builder unless they were brand specific, ie take a mopar to a mopar guy, a ford to a ford man, chevy to a chevy fanatic. I learned my lesson after taking my 440 to a machine shop where the owner and workers were all chevy fans, they made offhanded comments about "that ugly ole mopar block" and did a really piss poor job of vating the block and crank, i ended up having to run gun cleaners through the journals to get all the trash out they left behind, i assemble my own engines so i hate to think how bad it would have been if i were to have had them assemble the 440
