Working on a pair of these originally 572's now 580's for a friend, pulled the pan and looks to be flat tappet cam and lifters, can this be retro fitted to a full roller ?? check out the notching in the block for the long throw crank.


thanks for any input,

yes it can.all the mark4 blocks can be converted to roller cam.

thanks Mike.........I like spending other peoples money..

Edit: I just noticed the CARR on the rod bolt, must be Carrilo rods ?

i did notice that.i have those in my 588s and they are not cheep,looks like nice engines.

Are you running a solid roller ?

would the Crane #139651 - 244/256 @.50" with .632/.632, 114 be a good cam for the 580's Dart single plane intake and a dominator

not running solids.the 139651 would be a decent cam,a little light on duration but still a decent choice.
