409/409

I just purchased a complete 1966 390HP engine with a 321 CE block dated Dec. 1968. 3872702 heads, 3880827 & 3880828 exhaust manifolds, 3866948 intake manifold. All have 1966 casting dates. The crank has a 6223 stamped on it. It comes with a fan, pulleys, "444" bell housing, alternator brackets, fuel pump, distributor, water pump, oil pan, valve covers, and non original dual line Holley carburetor.
It is standard bore honed and new rings, new cam, rod and main bearings, new oil pump, new comp cam and lifters and springs, crank has not been turned. I was told the valves were lapped, but may need guides. Of course I will tear down to inspect and verify.

My question are:
How rare is a "321" block?
Is "444" the correct bell housing for 1966?
Is "6223" the correct crank number for 1966?
I would like it stock except for an aluminum intake and a cam with a mild lumpy idle. Any suggestions???
And finally, what is the value?

Is there a mistyping here?

You say it's a 1966, but also say it is dated Dec 1968?

FWIW.

It supposedly was a 66 390HP and the block was replaced under warranty. The replacement block is a 321 Dec 68 casting with a CExxxxxx stamping.

They are not at all rare, the blocks that are hard to find in good condition is one dated for a 66, the 321 block was not ever used in 66, there where a lot of replacement blocks in 66 the rod bolts where still coming apart. The 444 bell is correct, 702 heads are correct but also used in chevelles. The crank is a forged crank for 427 and also 396 chevelles, a lot of the 390 parts where 396 parts, intake included was used for 396 325 HP with EDH code and all 360 HP.

Not real rare. That's what is in my 66 - with 4-bolt mains.

Chevy built more 427 Corvettes and Impalas in 68 then 66.

Sounds to me the dealer only replaced the short block and reused everything else.

There aren't any 1966 parts in my engine.

Is 6223 the correct number stamped on the crank and is 444 the correct bell housing for a 66 390HP???

409/409

I meant is 6223 "cast" not "stamped".

JohnZ

Yes, that's a forged 427 crank, and the 444 is the correct bellhousing (the 444 is identical to the 621 except for the casting number).

Would anyone know a value on this complete engine and the other components mentioned above???

Mr D.

Well there is nothing special about the block so all you really have that might be of intrest is the 1966 unique parts.

Value is what someone is willing to pay or what one could expect to get in parts alone.

My guess is not more than $3k

Nowhere Man

If I could have bought a 427 long block for 3K I would not have a 396 in my Chevelle. 5-6K is what I see people asking and selling

Mr D.

What I was referring to was buying the parts to build a 427, crank, rods, pistons, heads, intake etc. The CE block is more special than a 454 block to build upon.

I'm also not talking a ready to drop in rebuilt motor for $3k, for that you would need $5k.

Nowhere Man

No 5-6K gets you cores to rebuild where I come from

Mr D.

In my neck of the woods $5-6k gets you a ready to drop long block.

Nowhere Man

A date coded 66-69 427 BB. I'm in the wrong area

Mr D.

No I'm sure that would push a little more. I just built a 427 last year using a 454 Block with 66 heads, intake and crank etc. I have $5k in the long block.

What does a 327/300 short block weigh and what does a complete engine weigh?
Also what does a 427 short block weigh and what does a complete 427/390 weigh???

Ralph,
Try Google all the information there.
You can also just put a set of heavy duty springs in your car to compensate for the weight of the big block.
