Is Big Sam Big Sam anymore with all these different people fiddling with his bits ? 
What is a Samuri these days ?

You didn't say that when Tim had a go at it and changed the sign-writing..........!

Albrecht Here is what I know:
Car was bought as a good running car,
Unsure if an engine build was planned at this stage, but car was dynoed.
It was from here the decision was made to rebuild.
During the engine strip down, valves from cylinders 2(in +ex) and 3 (exhaust) had bent valves, and valve to piston damage. There are a number of reasons why this could of happened most of them pointing to cam “phasing" (if thats the correct term) due to...
and/or inadequate ...
I will not tell specific details of the currents spec engine, because then YOU would also nearly know what I know.
Sorry Throttleton I was not PR-ing , I joined as I thought I would say hello and have a growing interest in these cars.
Sean I don’t think it will enter six hours at Spa, could be wrong.

More of a sprint than endurance build ?
Zs were made to wear down the opposition, whether in rallies or long distance races.

Can you clarify - was the car put on a dyno, or was the engine taken out and then dynoed? Reason I ask of course is that the power and torque figures you quoted will mean quite different things depending on whether they have drivetrain losses included or not......
Not forgetting that the power and torque figures you quoted were for an engine "with three bent valves", of course....

But seriously, if it were cam timing at fault ( is that what you mean by "phasing"? ) I'd expect all of the inlet valves - or all of the exhaust valves - to come into contact with their respective pistons. Of course, if you accidentally 'buzz' an engine then anything's possible.

No disprespect intended - these engines might be new to you, but they've been around for the best part of 46 years now and there's not that many secrets left in the box. Let's not kid ourselves that we are re-inventing the wheel here.

Count, please can you give the guy some slack here - all news is better than none so let's encourage it rather then hound 'em out.........Zen.
If all here know everything, how is it that there are still carbed Japanese cars doing under 12s when rocket science and big 'Woods' money here is still the wrong side on injection ?
Spa.........pré '65 ?

Ali68 please note I didn't use 'PR' in my post. I am very happy to hear what you can tell us now and in the future. Keep it coming.
If you know so much how come you dont tell everyone what YOU know. It may have been around for 40 odd years, you have told us nothing of the original engine. All we did to the engine was make it more useable, if the car had raced as it came to us, its track performance would of likely been poor then you would of probably said JD classics cocked the engine up. Not once have we said we have reinvented the datsun engine. Albrecht I have nothing more to say to you. If you would like to discuss this matter further, Please dont hesitate to visit us at the Jds Breakfast morning on 22 May. Our guest is Win Percy.
Sean will try keep in touch.

Sean - there's been more nonsense, tall tales and plain old fashioned bullsh*t talked about 'Big Sam' over the years than any other single S30-series Z in this country. It has only been robust questioning and some very dedicated research that got us anywhere near the truth, whilst sycophancy swallowed the tall tales whole.
I have no intention of being rude, but I don't want to hear any more blarney about this car. I believe Tim Riley did a good job for previous owner Nick Howell, and Nick himself was a good custodian of the car whilst it was in his hands. He did right by it despite not having a limitless budget, and Tim Riley built - I believe - an interesting engine that punched above its weight, again with modest resources. Tim is not here to put his side of the story, and I feel he needs to be defended.

Your employers already have the benefit of much what I know of the car. A big chunk of the research correspondence between myself and previous owner Nick Howell went with the car when Bonhams sold it. I recommend you have a read through it.....

That's because - quite simply - the car wasn't sold with it's "original" engine. The 'Big Sam' story involves more than one bodyshell, and many engines. The Tim Riley-built engine that was in the car when it was sold was a later addition in a very complicated story.
ali86 said:
I guess I'm not going to get any answer from you about bent valves and dyno figures, then? Oh well........
At no point have Jd Classics insinuated that Tim Rileys workmanship was of a poor standard. And the fundamentals of the car are still as he last assembled it. With reference to the engine we can only comment what we found when the car arrived. We assessed the car on arrival, attended some minor running issues, and ran the car on a rolling road (please note power figures include transmission losses) and have compared accurately with previous engine dyno tests. It was at this point we decided the characteristics of the engine were not suited to what we were after.
At time of rolling road test, engine appeared healthy (would you think it had bent valves at this point?), and ran cleanly to its max power at +8000rpms. Mike in an earlier post has quoted the current power figures correctly.
We do not know even if this is the engine that Tim built.

I don't even know why you bothered to reply
another point to me.
Races - indeed we are my dear Count - nuff said although it wasn't I that mentioned Spa as a possible venue
so an invitation perhaps ?Of course there has been a lot of dross written and 'myth' swallowed surrounding this car and Samuri in general, your efforts and those of others (?) to 'get the story straight' are applauded.....but you don't like it when I needle you for info so perhaps cut 'em some slack, cool off and speak privately with permission to write up findings here.
What I caution is not forcing a wedge between business racing teams with Zs and clubbie amateurs like the majority here and your fine self who've 'carried the flag' all these wilderness years.
There is a place for everyone BUT especially high-profile competition cars to 'up' the publics' and press' perception of our cars - it would be a shame now that this particular one has come out of the closet with the means to 'race' it that it should disappear into the mist again and us only read about its' exploits in the classic car press.
I'm not sucking up to anyone here but I do recognise that more frequently, the 'big boys' who've also access to the dosh necessary are becomming attracted to Zs and we should encourage that rather than sneer and be jealous (w/out inferring that anyone has so far).
A new Z ear - I keep telling you all !

Why don't you dig out that Big Sam spec sheet that lurked in some past Z Club mag and post it up here ? Tacky plastic bitz nailed on......sorry, I digress.

Either you admit to me being the GM and I'll do it or smear my face in your pigshit and do it yourself - I was thinking of Ebaying my collection of mags anyway.
