1970 L78 BLOCK 3969854

The only other possibility is it was a virgin pad block and stamping was added later by someone that wasnt up on date codes,just casting #s.Ive seen that many times . There is a way to tell in some cases if it was an OTC block that was later stamped . Ive never seen a lead time over 6/7 months in 20 years[and ive only seen 2 that far off], not to say it couldnt have happened.In this case id say its more than possible.

If stamped later it was a dam good job - I have pics I can e-mail anyone who would like to see. I be inclined to think this is one of those situations where a block sat around or as Kevin said - bottom of the pile. Nice block either way - it deserves to be built and ran again, it's been quiet for a long time. Also - June 1st not the 11th - brings it closer by 10 days

The 454 out of my 70 chevelle was cast in mid August 69 and the car was built the first week of May 70.It is her original engine.Almost 9 months that puppy was sitting before it got used. Heads , intake,water pump, etc are all within days of each other.

[/ QUOTE ] Most likely thats the case. The stamp date is definately June 11 not June 1..

Chuck I should have clarified in my last post I agree with you 100% on the lead time. I have not touched as many BBC as you have for sure but I have noticed your statement holds true except for 1970 it seems especially in the 454's.
When I checked my combo out with Mr.70 he indicated there was a delay in the release of the new design M22 which pushed some 454 engines back. Mine was a m22 which may explain the 9 months.Correct me Rick if that statement is not right.
Take care Joe

I have seen several cases of wide date gaps on 70 #854 blocks....we even have one in the garage. Block has a casting date of G 1 9 July 1, 1969....assembly date on the engine is T0701CTY... July 1, 1970...car has a first week of July date on the cowl tag...trans and rear are within a few days of each other. The VIN on our car is approx....14,000 units later than this car...so that looks good too. This Nova is completely documented and stampings are the real deal...
