Good thing I sold the car, or I would already have ordered this!

Cool head!  I always wanted a twin cam engine

$14+ is probably more than I'll ever be willing to spend

That head is a work of art.

I saw some threads when this DOHC was being developed, and I read an article about it on the Z Car Garage blog. https://www.zcarblog.com/2021/07/30/performance/datsunworks-twin-cam-power-for-your-l-series-engine.html

Z Car Garage has also worked on at least one Z with an OS Giken DOHC head.

It's a lottery purchase for sure.  I'd love to have the disposable income to buy that and have a 8000+ RPM engine built.

But the nice thing is that it's available. Z Car Garage was seeing 350 RWHP and was still planning on tuning some more. That's what a lot of guys are getting with forced induction.

The cylinder head has always been the primary bottleneck for power.

It is nice its available

Like the guy who ported and flowed the head for my race car says, “Its all in the head.”

I’ve been watching the development of this head since the guy first started posting about it on Hybrid Z. Fascinating, and something I would have if I won the lottery or inherited a huge sum of money.

But, *sigh*, I am but an average guy with an upper middle class income. Things like this are only a dream.

I could afford it, but then I'd have to sleep in the damn car after the wife figured out how much I spent on it.

The nice thing about living together with my woman, as opposed to getting married is that she has her income, and I have mine. We cover our joint expenses together, then do as we wish with what is leftover. We agreed 25 years ago when we entered into this partnership that we would do it this way, because the number one thing couples fight over is money. 

It must be working, as it has been 25 years and we have never argued about money or expenses.

Other things that we have disagreed about have always been trivial, and we wonder if the choice we have made about our financial situation has something to do with it.
