OK WENT TO CHECK(LET ME STOP YELLING) a D1VE 460 disassembled short block and i seen two things i have questions on. Fisrt the connecting rods were mounted to new pistons kool rt he says they have been balanced i can have that checked heres the but, the connecting rods had been machined on sides the cast marks removed, I've never seen that. He said that strengthins the con rod. What do u think?? :screwy:huh? ok n heres # two the block has surface rust all over it can that be chem bathed away and what about crank n cam seal n bearing surfaces cuz u can see they were resurfaced but surface rust is there. he aslo said the block had been bored 30 over if i took my digital calliper there what should it measure n with surface rust will bath be ok or honing is needed to resurface piston walls? Any help would be greatly appretiated :beer: :beer: :beer: :beer:s all around boys... TY

are you talking about the line that goes down the sides or the actual casting # in the center of the rod? i have heard of grinding the parting line off then shot peening the rod to harden it.

ok the cam bearings if you cem bath it SHOULD BE REPLACED, not sure about the bore. but i would assume its 30 thou over factory bore. if there is rust on the bores , watch out. it depends on how deep the rust is. each cyl is honed to each piston cause non of that stuff is perfect.

not the inside like u laid it on the table flat n see the hour glass shape of it but the side like the side u would see if stand next to motor and could see threw block u would see whole crank n con rods would look like half inch plates :screwy: that sounded so dumb if u turned it on its side with f#$^k let me find a pick n post

see connecting rod arrow above rod bolt thats been machined or ground not were arrow says i beam
-
rust on bore looks not too bad on opposite side of motor looks worse and no cam bearing is in there looks like block was machined then sat forever
-
spray it down with wd40 then.NOT WHERE YOUR GOING TO PAINT. sounds fine /remember clean clean clean and then clean again. no dust no dirt no hair just air.

Not easy to answer based only on your description. Generally, the surface rust on the block is not likely an issue to a shop; the OEM rods are cheap and easily replaceable if they have been more than just "smoothed" in the area you are describing. Crankshaft and camshaft journals are easily polished.
Without knowing what the asking price is/pistons part number/actual images of your concerns, no-one can tell you if the deal is worthwhile or not.
