Been 'away' from TC for a while due to work... but a friend has come upon a BBC and needs some decode info. So I thought this would be the best place for a quick answer.

The BB was removed from a 69 impala back in the 70's and has been sitting in storage ever since. Very clean inside...smells good (ya know what I mean)

Block Casting is 3935440, also cast is GM6, K2, pass, truck, perf, and 00NE2... cant find a date code...edit date is E268

Heads are 206's(edit) with dates of F225 and E205

Pistons are 3856247 with C1 and GM1 cast in as well. Heads are not off so dish/dome is unknown.

Deck stamping is CE870748

Any info about engine would be great, especially CR and possible cam. The engine seems to be untouched, rods are numbered with stampings, rods have reddish paint on them in the middle of the beam, steel shim gaskets, and 2 bolt mains.

Thanks guys

Block Casting is 3935440, also cast is GM6, K2, pass, truck, perf, and 00NE2... cant find a date code. Deck stamping is CE870748Casting number crosses to mid-to-late 68 and early 69. GM6 is a mold number, pass, truck, perf are generic. Date code should be on bellhousing flange. Deck code indicates a warranty C(hevrolet) E(ngine), made in 1968 and serial number 70748 for the engine itself. K2 & 00NE2 ??

Heads are 390's with dates of F225 and E205Heads first appeared on 67 396/427 oval closed units if they're indeed 3904390 and only used up to Jan 1, 1967. Dates are June 22 and May 20 respectively but the year (1965/1975) doesn't seem to jive. :confused:

Thanks guysI'd guess a standard 396/325 replacement fitted or short block with base 396/325 cam and typical 10.25 CR.

The info I have shows the 390 heads to be 1966-67 heads. Could it be that they are very early castings for use on a 1966 engine?

i found my casting date on my 440 block.down by the passengers side motor mount in small letters and numbers.

I added an edit above: the heads being 206's with 1965 dates and the block with a May 68 date.

Question: would these heads come on a 68 CE? or could have a dealer just replaced the short block on a warranty job? Could the original owner have bought a new 66 with the heads above, then had a problem and got the CE block in 68 and still retained the 65 dated heads OR is it more probable that the heads were swapped around over the years?

The CE date of 1968 is the date of the engine itself and doesn't mean it was made for 68 models only. Not sure just when the 5/50 warranty began but say a 66 had its engine expire in June of 1968 and was replaced under warranty. The replacement fitted (pistons, pins, rings, bearings)/partial (fitted block plus crank, cam, timing gears, and connecting rods) engine could be dated May of 68 (or March or April or even June) and installed. Usable existing parts would be reinstalled - heads, exhaust, fuel system, ignition, etc. depending on damage.

Since the engine itself came out of a 69 Impala, all bets would be off. No 65 heads and more than likely, no 68 dated replacement engine as it would probably have been used in another car long before the 69s original engine expired. If the 5/50 warranty was in effect in 1965, the engine could have been from a 65 Impala (dated heads) that had the engine warrantied in 1968 (dated engine) and later the entire setup was put into the 69. Purely speculation, but a plausible sequence. :)

Thanks for the help Dale...and all.

It is a puzzle for sure as the engine had a short pump with left mount alternator and a long pump style P/S pump as well as hard carb linkage.
