LS6 Pad Stamping
 

I am looking for a 454/450hp LS6 Manual block to put in a 1970 Chevelle. I ran across this block and was looking for opinions on the stampings. It is too easy to make a $500 block into a $5000 block with fake stampings.

Right off, the VIN is too early to be from a real LS6.
LS6 production started in December `69, and this VIN is more like October of `69.

It looks like the broaching ends and is smooth the rest of the pad. Looks nicely re-gangstamped to me, too nicely. I've seen restamps from a guy in L.A. who does very, very similar work. Just my $.02US.

For info, my LS-6 was one of the first few built and it had a mid December engine build date.

Is the person selling that block standing in front of it,or behind it?..and who is it?

COPO.......where have you been?

What's the block casting date?

Re: LS6 Pad Stamping
 

This block casting date is I-16-9.

I have not pressed them very hard for any history on it or if they will back it.

Anyone have a legit CRV block to sell? Or reasonably priced CRV (or possibly CRR) complete running motor?

Re: LS6 Pad Stamping
 

A few days ago I posted an ad for a standard bore CRR. Check the ad and call me if you want pics. You would be welcome to post the pics on here for opinion of the experts.

I think there are more LS6 cars around now then were made in 1970...

A few of those &quot;broach&quot; marks look a little skewed...

Re: LS6 Pad Stamping
 

Here is the block that is being questioned. BTW..Looks fake to me too.

Re: LS6 Pad Stamping
 

-----Why under &quot;engine&quot; is this block described as a 6.5 liter 396??? Somebody hedging??? Also, who has looked closely at the casting #s? Several look too far off to me.

I got a response from the seller - said he thinks it is a restamp. Nice of him to mention this in his auction. Guess the winner will find out the hard way when they get a worthless $1900 block.
