I just got the first 440 Source kit in my shop--
Here is what I found:
Pistons were a dish no one else offers except order and wait so they were a Bingo!
Crank was on low side everywhere--so she turned like hot butter another BINGO!!!
Rods ehh...honed pins to fit like normal

Big deal is the crank seal area--It is SMOOTH like they SHOULD BE!! I am done with the "hash mark--deep gouge"-BS on Eagles! No more Eagles in this shop with that mess back there--They need to SOBER UP!! and quit doing cranks that way like it is 1962.....I think they are idiots for keeping that up
So...I am impressed a backyard guy would come out fine with what I recieved after he pinfit the rods --they also mentioned that when I ordered!!
Think they should go ahead and do it for folks to improve their kit but ......silly not to--easy way to imprve their offerings--

Me likey so far....
