what is the M2 stamped on my motor mean?

[ricky]

i have a l16 in my 510. and was wondering what the m2 was stamped on the side

[izzo]

Omg! If its stamped M2 on the block, that means its a really rare block. only 4 were ever produced.

 

haha, kidding. its just a stamp, search the site for M2 there was just a recent history lesson on it. you might have to type "m2" with quotations because of the search system on here...

If it looks like this...

 

 

It's a very late model L16... like 1979 or later crate engine.

Hey whats up with the road draft tube(PCV) hole on that block? Is it even there or has it been moved?

 

My L16 is also missing some of the holes for the AC/smog pump bracket. Guess it must be an early one.

The block vent hole is still there at the top right just like the L20Bs..
