Good job now send it over here and I will make sure it works OK and give you a mark out 10....PS you only have a couple hundred more to do to catch up with me.
😆😆😆😆😆😂😂😂😂😂😂😂

Thanks for that

Not sure what you are allowed to do to your motors for the class you run.
We are allowed to do anything we like as classes are 0-2000cc...2001.etc etc.
My A12 has A14 77.5mm semi flat top 3cc dish pistons,ithas com ratio of 12.8=1...on E85 fuel.I had the little ends reemed out 2mm to take the A14 pin(been reving the crap out of it for 8 years with no problems.
Cam starts to work 5500 and flat lines at 8600.was able to rev to 9500 if needed without loss of power.Has 39mm inand 33mmex valves.2x45mm webbers.
Last time on dyno 99bhp at wheels.
E85 fuel is bowser fuel and easy to get and is cheap HP but you use a lot more of it(about 1 litre per kilometre)but the power is fantastic.what else can I say I have been building Datsun motors for over 50 years and only 1 blowup(and it was big time and big money).I will just use old faithful 1321cc this season much to my disgust as I am up against 2000cc cars.GREG.
PS if you want to know anything else just ask.
PPS What bore and stroke is an A12A and littelend size.We don't get to many of them here'

Tom there is an incar video on Facebook. Just type in Greg Sutherland you may find it because I can't put it up here
PS if you are on facebook let me know

The GX head I am still using was one of Peter Zekerts damaged units.He fixed it before I bought it and I have repaired it once more a few years ago it has a chamber of 20cc and 39mm inlet 33mm ex.They are worth repairing here as they are $1000AU for a bare head approx. PS any damaged heads freely accepted 😆😆😆

The bottom pic was last race last year it broke 2 rings hense its a bit smokey
A quick rebuild for this year.Have to put some thought into what to do with the blown 1510cc motor????

New 2018 paint colours(retro serca 1970s Datsun 1000 sport sedan )
Still running the 1322cc motor unfortunately.

That's OK it's good to hear what you guys do to your engines which is a lot different to us. Greg.

Thanks for the imfo.
I have 3x79mm head gasket spare I probably won't use.
The 1510cc was getting 120hp at the wheels but not for long.

You forget there is 200 million of you and 20 million of us and the lastA series car here was in the 1980s and we didn't get the 63a boxes or that many 5 speeds
