sss m1 block

[datsunfish]

So dude says that dude told him his L16 block was a sss because it has M1 stamped on the block.It had a stock open port 210 head.Said something about being fully balanced.

As far as I knew all L series cranks were fully counter balanced.Every one I have opened up has been obviously balanced.The reason I am wondering about it is that I have a L16 in my 521 without M1 on it but I have an old block in my yard with the M1 stamp with a good crank.If it is better than stock it could go in my other L18 block.

sounds like something to ask hainz

M1 blocks were just newer. I have an M2 L16, made in the LATE 70s (maybe even 80).

My '73 L16 has 14 210 M2 stamped on the block.

 

What's an sss?

 

Isn't balancing a process where the crank is machined to be highly balanced? Maybe that is what the guy meant?

L16 are not fully counter bal

I believe the L18 and L20s are but I have to look in my book

 

a L16 w ith a 210 head is what I cALL STOCK. hE HE SAYS MORE ITS JUST BULLSHIT

The M2 block I have has the late model type PCV breather and has casting marks for a NAPZ-Z, which is why I said mine is late 70s. But the M# could mean nothing.
