decode 440 blk

Well thanks all for input..was just wondering what vehicle it came out of since its is a forged crank 440[std bore] with flat-tops in the hole just .038 and no valve reliefs..in which I'm fixing to flycut some in[valve reliefs] so I can use this motor in my dart with a comp xe290s cam and 77cc 906 heads...prob have to use a 2'' spacer just to get the comp down...har har lol...and yes the pistons are cast and the thickness is .495 so I can safely notch them up to .200 but prob will be around .100 or so...am going to mock it up and see where it all starts to rock and roll and go from there...gonna try for low to mid 9's comp and run pump gas...hopefully that will work....may not..may have to go another route entirely.....
