LZ9 Flow numbers?
Anyone know what the cylinder head flow numbers are for a stock LZ9?
Also, has anyone flow benched a ported set?
Inquiring minds want to know.

Thanks for the responses.
It would seem to me, that as a site, we members would want to know what a stock LZ9/LZ4 head flows.
This would help in promoting this engine.

Well go out and buy a flow bench, a set of heads, spend the money to port one, do all the testing, and let us know.
Shouldn't cost you much.
Then YOU get to be the guy with the FREE answers.

Well, if you 70 BBC C20 is so great, why are you wondering about the head flow of a LZ9?
But seriously, there are only 2-3 people on the site that have really even messed with the 3900. So its not like this is a SBC or BBC head that hundreds of people have messed with. Sorry we can't provide you with all the answers.

I asked a simple question in good faith (after doing a search)and after several people gave me polite responses, I get a rude, SMART ASS response from another member.
As for my BBC C20, yes it is quick, but it is my work truck and has nothing to do with my project 240Z.
I have a friend that has a speed shop that does porting and has a flow bench, so I could get the flow numbers.
