Yes it is built to some extent, although I am not aware of what has been done internally I am pretty sure its been a couple of the more standard upgrades. I am sorry for being vague but I would feel uncomfortable guessing at what has been done to it in the case that I'm wrong. Youngbuck, if you have any more questions or are a serious buyer please PM me.

My zip code is 77494 for those looking for a shipping quote.

i am interested im swapin like my sig says. gona turbo down the road an only wanna build the tranny once, need it 2 handle bout 600hp to the wheels.

 

I'm assuming with that compression ratio that you have flat top pistons?

 

That is correct. 4.030" forged flat top pistons w/ -2cc valve reliefs on forged stock length mahle rods on a stock LQ4 crank.

 

Bump for the day. Might have a deal pending on the short block but I am willing to make some deals on the prices if you want multiple parts. (entire intake/ nitrous system for example)

 

What would the comp ratio be on a stock #317 head?

 

I don't know, you would have to ask a professional to do the estimation. I'd say most of the increase in CR comes from the work done to the heads.

Sale pending on short block.

 

The short block has been sold and some new parts have been added:

Morel solid roller lifters, Cometic head gaskets, hardened pushrods...all never been used.

PM me if you are interested in ANY of these parts and we can make a reasonable deal. Prices shown are asking price, some more set than others.

 

bump.
