Re: Nissan twin cam race heads for A series, were they ever made?

That is the Twin-Cam head that was just sold Sunday at auction for $5000


The auction title was Quote:
NISSAN Sunny Excellent Racing Head Twin Cam Head for Race Nissan Works B110 B210 B310 TS Sunny TS1300
Yes, that would be the LZ14 engine which was used in the 1973 Sunny PB210 race car


The auction description was a bit confused:
Quote:
サニークーペエクセレントに搭載されたR390型エンジンのツインカムヘッドだと思いますが、資料が少なく断定できません。
非常にコンパクトなのが印象的です。 [I think it's the twin cam head of the R390 engine installed in the Sunny Coupe Excellent, but there are not enough materials to be sure.]
However, the Nissan R390 was made in the 1990s, used a V8 and was not a Sunny variant. The engine used in the Sunny Excellent was an L-series engine, and the twin-cam racing version was the DOHC LZ engine


All our previous LZ photos show square covers over the cam ends:

But Nissan Global explains Quote:
The head cover has a rounded shape that is different from the later flat type
Yep, hard to see, but the early LZ race car seems to have them. Here's a photo from the old ratdats site:

That seems to match the auction photo:

and final confirmation, the combustion face photo matches the photo from Nissan Global:

Here's the last photo from the auction. I think its the exhaust ports
