All -

Some time ago I posted asking what if any problems I might have if I was to aquire a 1983 F250 4x4 with the 460, and swap it in to my 1978 F350 Super Cab Trailer special 2x4.

The answer was is would go, and there shouldn't be any issues.

I did notice through going to two autoparts stores and asking for price/availability on the following items:

Head gasket
Oil Pan Gasket
Valve Cover Gaskets
Intake Manifold Gaskets
Exhaust Manifold Gaskets
Oil Pump
Water pump
Carb Baseplate Gasket
Timing Cover Gasket

Etc, that the only notable difference was the Carb Baseplate gasket was the only difference, and that was because the 83 was a Emmisions compliant.

However, here is my delima. After removing the power steering pump it was clear that the this 460 was not the original engine in the truck because of the huge hole in the crossmember someone had used a cutting torch to remove to allow for the oil filter to fit.

So, my question is, how can I tell, if at all, what year this engine might be, or what it may have come out of?

Is there a difference between a Car 460 and a Truck 460? And if so, what?

Thanks,
-Chris

 

the only real differences between the car and truck 460 are the exhaust manifolds and the oil pan... car is front sump and truck is rear sump, and the car got emissions crap before the truck. check the sticker on the valve cover, that should tell you the year. if thats not there just look at the heads... the casting number is in plain sight between the valve cover rail and the exhaust manifold. itll probably be d3ve- which is what came factory from 1973-1987.... up until they changed to fuel injection in 1988. you can look for the casting number above the starter too... itll probably either be d9te or d1ve... d1ve is from 1971-78, d9te is 1979+. no other real differences.

 

When I swapped my 460 in my 80 F-350 4x4 from a 78-79 F-250 I had to change the oil pan, oil pump and pickup and cut a hole in the crossmember to clear the oil filter. So i'm guessing your 83 has a 70's big block in it so plan on a new oil pump, pickup and pan for your truck. If I remember correctly 84 was the first year they brought the 460 back.

 

The last FoMoCo passenger car to use a 460 was the 1979 Lincoln Town Car. The 460 engine was not available for passenger cars in CA in 1979.


NOTE: D1TE-6015-AB Block was used 1971 thru 1979 <<<

D9TE-6015-AB was used in 1979 and later.

TWO DIFFERENT 460 ENGINE BLOCKS USED IN 1979

The flywheels, and vibration damper are casting number specific. D9TE-6015-AB uses a weighted spacer, D1TE-6015-AB does NOT!

>>> Taken directly from the 1973/79 Ford Light Truck Parts Catalog:

1973/79: D1SZ-6375-A .. Flexplate = use with D1TE-AB

1979: D9TZ-6375-A .. Flexplate = use with D9TE-AB
======================================

1979: D9TZ-6316-B .. Vibration Damper = Use with D9TE-AB

1973/79: D4VZ-6316-A .. Vibration Damper - Use with D1TE-AB

 

Bill you have one thing wrong in that post probably just an oversight I am sure and that is the D1 blocks were listed as originally linclon motors thus the casting number is D1VE not D1TE, the T or truck designation wasn't used in the casting number until the D9TE blocks came out.

 

Yes, you are correct, it is D1VE, not D1TE...my bad.

 

It appears that the motor in the 83 is older than 78. The heads are D3VE, are they good, bad or average? What is the casting number of the "best" heads for a truck for a 460, and what are some "good" castings numbers, and what are bad casting numbers?

TIA,
-Chris

P.S. Haven't gotten the block Casting yet...

 

the D3VE heads were used clear into the mid 80s without that casting number from the block you can't tell if it's pre or post 79 engine, heck D3VE heads might actually be original in a 83.

 

One other slight mistake. The last year for the 460 in
a passenger car was 1978. The 79 Lincoln's only used
the 400. At least that's the info I have. The 460 was an
option in the 78 Lincoln. It was last standard in the
77's.

 

Okay, so I got the first layer of crud off this thing and it is a D1VE block. So from what it says above, that is the correct block for my truck (1978 F350 TS 2x4), I just don't know what year it is, or what it came out of?

What about the other letters and numbers after the Block number (D1VE) and the Head number (D3VE), are they of any significance?

Based on the D3VE head casting number, what size are the intake and exhaust valves?

Thanks again,
-Chris

 

intake is 2.08 and exhaust is 1.66 stock, actual year doesnt matter as the engine didnt change from 1973-1978 at all
