L33's Increased Hp

[Mitragorz]

I've got an '05 Z71 with the L33. For as long as I've had it (bought new ), I've heard that it was a 15hp increase from the iron-block. 310HP. I think I pulled that number from wikipedia a few years back.

 

Recently, I've been reading online (wikipedia, and some other sites) that the L33 has 35hp over the LM7, making 330hp. (http://en.wikipedia.org/wiki/GM_Vortec_engine#5300)

 

So... Which is it?

I'm pretty sure it's the 310hp

In 2005 it was 310 HP.

 

This is from the 2005 Dealer book.
