351W guys, gotta question

I went to the local junkyard today, and found a 351W in a 78/79 F150 truck.  The decal on the side of the driver side valve cover was worn out too much.  It was lettered in a darker blue than my '76 Torino 351W is.  autolite carb has C8AF AK on the tag.  Anyone got a way to quickly identify what year this engine is?  It doesn't have air injection ports.

OK, it should say got a question, not gotta question, lol.

feel free to move it to the appropriate forum.

if you're able to, take the valve cover off. the number/mold year code should be casted right on top.

but keep in mind thats the year casting of the heads. the block is probably different. i'm not sure which one you need specifically

yup, but that may not be the original carb, too. casting number for the block is located above the starter.

yeah, I suppose I could bring an inspection mirror.  Heads are the same throughout all the earlier years anyway, right?  Is it worth getting them, or going for the e7's?

I should say I'm looking to rebuild my '76 351W, and I'm not keen on the air injection heads.

69-71 heads are about the best stock windsor heads you can find.

thanks a bunch.  Should be a build date under the valve cover, right?

yeah and they are getting c00ched up left and right to.  stang guys down in carolina are diggin them out of every bone yard they can find.

from my diy link above my sig..........

*******drill head bolt holes larger if used on a 351w.
351*/ 71-71 /  The 351 Boss was a one year deal... '71 ONLY... In '72 & '73 a lower compression Cobra Jet 351 version was available that was similar to the '71 Boss motor... A few Torinos got the CJ in '72-'73 in addition to the Stangs... I'm assuming the Mercury models received them as well...turbocoupe50.

Ford 335-Series Family
The 335 Series consisted of versions of the 351 and 400 blocks. It lasted from 1970 to 1975.

351 Cleveland
canted-valve cyclinder heads.
bore and stroke of 4.00 X 3.50.
a light weight block to beat.
one of the most desirable V8 engines Ford had to offer.
a two barrel or four barrel setup.
From 1970 to 1971 the 351 boosted between 250 to 240 horsepower.
As time progress, the 351 Cleveland saw lessor horsepower until its' demise in 1975.
the 351 Cleveland four barrel came with dual exhausts, a higher compressions ratio, larger intake/exhaust valves and four bolt mains during the first year of production.
the 351 Windsor, which belongs to the 90 degree V8 family and bears no resemblance or connection to the 351 Cleveland.

351 CJ
Introduced in the fall of 1971
mostly of four bolt mains, however there are some with two bolt mains.
possessed a spread bore bolt pattern cast iron manifold
Autolite carb 4300-D
Horsepower varied from approximately 280 during the first year of production down to 265 by 1973.

351 Boss
Most desirable
only available in the 1971 Boss 351 Mustang
Four bolt mains
high nodular iron crankshaft
solid lifter camshaft with screw in studs
adjustable rockers
an aluminum four barrel intake

351 HO
In 1972, Ford rolled the 351 Boss over into the 351 High Output for the new year.
Slighltly less desirable, the 351 High Output used the spread bore bolt pattern cast iron manifold
Autolite 4300-D.
With a milder camshaft, the output of the 351 HO was about 275 horsepower.

351 M and 400
By 1975 the 351 Modified was issued with Cleveland heads
a two barrel carb.
hydraulic lifters.
a cast iron intake manifold.
a two barrel carb.
the 351 Modified and the 400 which was introduced since 1971, are virtually identical with very few exceptions.
