LZ9 Flow numbers?

[Z-Dreamer]

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.

So nobody knows?

I find this hard to believe.

Some guy was trying to obtain a head for flow benching.. there was a thread...

[Superdave]

they haven't been posted yet..

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.

p.s. My 70 BBC C20 does better than 14.22! lol

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.

Since this will be my last post here, I want to thank the members that showed some respect and a willingness to answer my questions.

If you get numbers, please let me know as I would love to compare with another setup. Make sure to get the bore size used and the depression.

You're right, I'd hate to see some of the crap that I've seen on the Fiero forum start up over here. It makes Fiero owners appear to be special needs people from a social stand point.

Go take a look at the mis statement thread of needing a pilot bushing or your manual tranny can blow up. 7 pages in two days, of mostly grown ups hurling insults and that's not including the second thread on the same topic started by the same individual on about the same day as the first.

Z-Dreamer's inquiry and surprise is somewhat of a compliment regarding the wealth of info here and his knowing this is the best place to look. I usually refer fiero owners curious about the aluminum head motors to this forum. I'd hate to have to apologize because someone was less than welcoming.

I looked into trying to get some flow numbers but no one I contacted seemed to have the equipment or direction to it so I stopped bothering accepting their appearance as proof enough they will flow a lot of air.
