I think all 460s built after 1979 were externally balanced. 68 thru 78 internally balanced and heavier blocks.

It is external after 78. The 3ya is also is missing the oil slinger on the rear. Why? Also 79 and later blocks will not take a stroker crank without grinding the block in most cases. As far as interchange, i would stick to internal balance when possible. The closer the counterwheight is the better! The way it was explained to me 25 years ago, "tie a string around a rock and make the string 6ft long. Stand and swing the rock in a circle. Can you keep standing the same spot? Shorten the string, and you will!

doesn't the 514 use the truck block??Also why are the cylinders longer in the (D9TE)truck block 6 1/4 long and 6in in the (D1VE) car block,Can the 3YA crank be swaped out for the earlier one?

205.158.104.42 REAR Oil slinger...?

"...missing the oil slinger on the rear"?...Interesting

I only knew that some of the earlier engines equipped with an oil slinger at the FRONT; located in front of the timing chain drive gear. Do you guys think these disc slingers are really necessary anyway?

Don't leave it out or you will have a heck of a leak!

Gary:
#1) I assume you're referring to an oil leak because of not installing a FRONT oil slinger?

#2) I'm guessing the leak comes from the timing cover crank seal and is due to oil "piling up" at the gear and overpowering that seal, is that right?

#3) Did all of the 429/460 blocks come with front oil slingers or are there only a few years that require them?

#4) Would using an aftermarket crank change the need to use the oil slinger?

Thanks, StickBBF

Some aftermarket timing sets tell you not to use the slinger. Space prohibits it.I've left them out with no problems. The slinger i refered to was in the rear of a internal 429/460 and missing on the 3y series.
