Are you talking about the progression holes?
Tel, maybe it's my eyes but in that second pic is that a crack between the headbolt hole and water ways in the top right corner?

I know this is a little off thread so I apologise to the OP however I will bring it full circle
.
At the risk of appearing antagonistic (for which I apologise)
No offence intended but
Sadly there was no specific "Samuri" formula, spike fitted what spike had on the shelf (or elsewhere) at the time, so the "it’s a samuri" label is of little value, I had a pet snail called Ferrari but it was still a snail.

The advice to get it on a rolling road (or chassis dyno) is excellent and vital, after all if you can’t measure it how do you measure improvement, most triple setups have been bolted on with little attention to jetting and linkage condition and as such probably 70% of installs can be improved significantly.
So firstly it’s important to understand what you have and then get the best out of what you have
1. Get it rolling road tuned, this will hopefully help iron out any current issues and you will have an “idea” of its current power output.
2. Aside from everything else, ask the rolling road engineer to measure certain aspects of the cam such as lift and overlap, this will give some indication of what is in there.
3. Have them compression and leak down test it.
4. Find out what distributor set up are you running, stock or 280ZX etc
5. Look closely at the exhaust system (vital) and post pictures
6. Post pictures of the carb, linkage condition and air filtering arrangements are vital to the smooth running of the system.
When you go to the rolling road, listen and ask questions, is it flywheel or wheel horsepower, how are they calculating coast-down or rolling resistance, get sample graphs and share them
If once they have done the business you are still not happy with the power then a re think and plan is needed
Consider what are you after, a fast road car, a ninja road car or something to go to Tesco’s in
Have your wallet ready.
To get 200 BHP (flywheel) out of a 260 isnt to difficult but there will be a cost to do it reliably
Assuming that the carbs and manifold are good (big assumption) the cam is stock, and the engine in very good condition (leakdown and compression good) a compression up lift along with a cam change may get you there, it all depends on what you have now.

Hello Guy 600n, am new to the website, but have a little background info on your car, it was restored roughly 10yrs ago, bare metal respray which looks to be holding up pretty well only cost me £1500 for the whole job. The triple dellorto,s were supplied by Geoff Gale who used to run auto-active in Bristol he did most of the resto work. She still looks very nice in that lovely orange, chose the colour myself. Nice to see her again. cheers

The car has been resprayed since it left auto active hence why it still looks very nice ( in the last 18 months)...If you look carefully, its not the same shade of orange as when it left auto active

probably toned it down?
Thanks SKiddell! i will have to take it back to the rolling road and see where to go from there then.
I took it to a rolling road a few months ago and the guy gave me a load of free 'o' rings and filter things, then said, 'go fit them and come back to me, otherwise today will be a waste of your time'.
I'm going to try do these bits this weekend, and then we will go from there.
thanks guys
Nice to hear from you! such a good choice on the orange, but i have been told it was sprayed again more recently (not that i know exactly when). it is still in fairly good condition, but i do need to get some of the panels re-aligned and the doors too.
it sounds bloody ace though!
