I bought a complete motor (460) and tranny (C6) from a friend, when I started pulling it apart I kept track of the numbers on certain pieces.

Block=D1VE-6015-A2=1971
Heads=D3VE-A2A=1973
Connecting Rods=C9AE=1969
Harmonic Balancer=D4VE-AA=1974

 

block is a 71
heads are a 73 casting, big chamber=low comp
con rods are a 69
and balancer is a 74
I'd have to look in my book on the balancer but it might be internally balanced, if it doesnt have an eccentric balabce shaft between the timing gear and the balancer than it is

 

A member at 460Ford.com said it's a 1974, just curious,good to know when I start buying parts for it.

 

There is nothing in what you posted that would tell you it is a 74. The ONLY thing it tells you based on everything and assuming everything is original is that it was made AFTER 74, but before 79.

 

DIVE-6015-AB, -AB1, -AB2 = Bare Block Casting Numbers.

1971/73 429 / 1973/78 and some (F100/350 & Econoline) 1979 460's.
--------------------------------------------------------------------
D3VE-A2A = D3VZ6049A .. Cylinder Head

1973 429 / 1973/76 460
------------------------
C9AE = I could not find a cross reference for this rod, but the rod bearings are the same 1968/73 429 (except Boss 429) & 1968/79 (prolly later-I didn't look) 460.

D9HZ6211A (replaced C8SZ6211A) .. Rod Bearing.
----------------------------------------------------
D4VE-AA = D4VZ6316A .. Harmonic Balancer-Use with 460 engine with D1VE block casting numbers.

Fits: 1974/78 460 and some 1979 460's.
---------------------------------------
In mid-year 1979, Ford changed the 460 engine, the block casting number is D9TE-6015-AB. This 460 uses a weighted spacer, the D1VE blocks do not.

The harmonic balancer and flexplate used with this 460 are not the same as the ones used with the D1VE blocks.

Passenger Cars are not affected by this running change (there is no before/from a certain serial number or production date) because the 460 was no longer offered after 1978.

You cannot go by casting/engineering/part number prefixes to ID what years the part fits and/or what it is from, you wanna know why?

Ford is in-famous for replacing (updating) 10's of 1000's of part numbers EVERY YEAR! The rod bearings are a typical example, the reason why I typed the part numbers.

Keeping track of all these number changes was...and still is...a full time job in itself, and a royal PITA!

btw: This is...at least...the 100th time I typed the info inre to 1971/79 429/460 block casting numbers here on FTE. The info comes straight from the 1973/79 Ford Passenger Car & Light Truck Parts Catalogs.

 

Thanks, Rob and Bill for your information and time

 

I recently acquired a 1976 F358 SCS which the PO told me has a rebuilt 460.

It's impossible to correctly time this engine -- as the rubber in the "harmonic balancer" (correct FoMoCo terminology?) is shot.

The number stamped on the existing "balancer" is D0CE-B. But since the engine was rebuilt, who knows if the correct part was used?

What is the best way to determine the correct replacement "balancer"?

This looks like a possible NumberDummy challenge?

Thanks -- this site is a wonderful resource!

same deal here...Ok no more beers

 

The date of production of the block can be found in the lifter valley example: -5D19- which would translate 1975, April, 19...same deal for the heads, look for the date cast
Example: -9C21- translates 1969, March 21 (keep in mind this head was a sixties casting C9VE)

 

look behind the balancer and see what type of spacer it has in it. if it has a plain round one then it's a 78 or earlier, if it has a hatchet weight behind it's then it's a 79 or later externally balanced engine. Only real split you need to know on the light duty engines.

Now that is the figure out the 'correct" version. But honestly all the balancers used on these engines were neutral balance and it used the spacer for the inbalance unlike the small blocks that it was done in the harmonic dampener itself.

Other then that look at the block above the starter for a casting number. it will get you in the ballpark. Personally I would go ask for one for a 76 ford car with a 460 in it. just make sure it has the timing marks in the right place for your timing pointer. (you know compare to what you have) Also make sure it has the same mounting holes for the pulleys. The balance itself will be the same.

 

Looking near the starter revealed a D1VE-6015 block number. Which means it has an internally balanced 1973/78 block, correct for the 1976 MY SCS.

Checked a couple of Ford parts sources for D4VZ6316A balancer but came up dry (obsolete).

So I ordered a Professional Products "PowerForce" 80008 Harmonic Damper.

Should have it in a day or two and will re-check timing once it's on. (Used the TDC mechanical verification to find 0 degrees.)

 

I have used and like powerforce dampeners on my own stuff.
