Title: MQ Block
Post by: L78 steve on January 19, 2015, 09:50:24 PM
I found a needed MQ block. A bit early for my car but better than what's in it. Is it possible for a TO405 MQ to have a E-10-6 casting?

The picture shown is horrible for determining much of anything.
Are you absolutely sure it is an E?
Do you see any visible signs of what may be a repair of the block?
I can come up with a couple of reasons a block would sit for 11 months before being built.
1. A repair needed to be performed or
2. It was uncycled inventory (by uncycled I mean a FIFO inventory system was not being employed.)

That being said lets talk about the block, ... the deck looks to have a decent amount of rust pitting, make sure the pitting is consistent across the stamping, in other words makes sure there are pits in the stamp character impressions and they match the rest of the pitting.  

As far as an assembly date being too early, I do not believe there are too many norms associated with 67 L78 production, there were too few built in the 4 months they were produced in order to draw many meaningful conclusions.

Bergy worked at Tonowanda he or JohnZ may be able to elaborate on the inventory procedures and whether it is possible and if so, the probability of it happening.

I know the pic. is useless. It's going to a shop so maybe I can get them to get a detailed pic. The assembly date is at the start of 67 L78 production so I guess its possible the engine parts could have been sitting but 1 year? The VIN stamp has multiple strikes. VIN is 7N208512 which makes sense for the assy. date.

No, it's not, unless the foundry service worker who made up the brass casting date tag for the pattern made a mistake; a block can't be machined and assembled before it's cast. I didn't see a photo of the casting date.

Wasn't the block cast May of 1966?
If these numbers are right the engine's assembly would be 10-1/2 months after being cast, correct?

Correct E 10 6 cast. 0405 of 67 with a VIN of 7N208512.

That block might  have been for one of the last 4P l78 cars before they became 4k.

So someone could think they have a SS350...
Did anyone check that VIN 208512 against the Yenko list?

That may be where the guy that has it now got it. He claims he paid 2k for it.
