hmmmm sounds like a job for my local speedway engine builder Bryan Moyle, he can do the job for an extra $300 more than I can do it but at least it will be done right, he will also machine the crank and bearing journals if they need it which is reassuring for me, when you live in WA an A series engine can be a hard sourced part.
So if this one gets arsed up I am packing up and moving to the eastern states! I can't afford the courier costs anymore!

Ok I am in the process of looking at rebuilding my bottom end with new main, big end, small end, and camshaft bearings, new pistons, new rings and all the associated gaskets, I am unsure whether I should pull the engine out, dissmantle it and take the bare block down to be honed then measure the bores to work out if I need oversize pistons or just replace the components and leave the block alone? it would be a lot quicker to just swap the components with new ones than to have the hassle of honing measuring and ordering specific size components, has anyone done a rebuild without honing the block?

also could try stuart wilkins here http://www.swmotorsport.com.au/

so what kind of power increase could be expected by bolting this on top of a freshly rebuilt A12 bottom end from a 120Y with electronic ignition and a 2 1/2" exhaust system? I know theres no way of looking into the crystal ball but it would be great to to have some idea

what size valves? what sort of side draughts? cam spec? double valve springs? I desperateley need some extra power!

would I need to modify my fire wall to fit this engine? I have a 1200 automatic sedan so hopefully the transmission tunnel would be big enough

what ever happened to that "supertune your A12" article? If I remember that explained that a power increase of 52% was possible by tuning the standard engine

I have just noticed that I have a terminal on my distributor with no wire on it. The terminal is behind the vacuum advance diaphram, anybody have any ideas on what it is used for?

here ya go!

Bugger I live in Bunbury which is 200 odd km away but it would have been worth the drive just to see some classic's I had a blue 1200 ute following me down a dark country road last night which is a new one in bunbury I just noticed, we need to keep in touch more often and stick together
