I'm on learners. It's nice knowing everythings fresh. Well a weber, mild cam and a fresh build with a slight skim off the head with make for a nice engine. Won't be a huge difference bit it'll be nice. Otherwise an oval port head ( h75 or h89) if u have the extra dosh.

Where abouts are you located? What carb are you running, and dis you have to send the cam away or are you near them? Also how much did you take of the head, and did you ressurface the block too?

I'm in Melbourne so Wade cams isn't too far away, plus there is crow cams that are fairly loc to me also. Both well known.
I'm running a single 45DCOE weber on the d1200 manifold that has had the flanges or whatever chopped and it's had the oval port Andes welded on, works ok little dodge but good enough till I buy a set of twins. I've choked the weber down a fair bit so that it worked on the a12.
I'm not sure how much has been taken off of the head as I brought it after someone had the ports polished with bigger valves and the head had previously been shaved so I only had it machined for a freshen (skimmed). I would talk to your mechanic for a better understanding of how much to take off, or have a chat to member bige. Also don't forgot my head is an h89 oval port head so it's different to the standard a12 round port one.
I didn't need to have my block surfaced as it had been hot tanked and was in good condition. before I brought it. I did have it honed though.

Would they even know you did an engine swap?

Pretty sure one of the ID plates has what engine size should be in the car stock, plus the engine number is on the side of the block, not that hard to look for...
AND if you were to work it or put a set of carbs on thats a dead give away...

I forgot you guys have yearly inspections over there. Here if it's licensed I don't see how they would know

We don't have yearly inspections, however we do need to display P plates (probationary license) therefore making us the epitomy of ordinariness in the driving community (according the law, statistics and well everyone else...) thus making all p plate cars absolute cop magnets.
Coppers are checking cars more closely and having massive crackdowns throughout Aus, especially Melbourne and Sydney.
If we're caught with a modded engine, then it's an instant defect and big fines for the driver, then it's back to square one, the little old A12! Then all of that work building an A14/15 is money down the drain as you'll never get it back trying to onsell it...(don't quote me on those laws either...)

I just looked, you're from WA lol. I didn't even look and assumed you were from America or something :S haha. Whoops. Eitherway doing engine mods here is hard with the cops. I'm in melb and get looked at constantly, haven't been pulled over yet though touch wood. (probably due to the L plates, the tend to leave us alone...) but you wait as soon as there is a set of p plates being displayed I'll be looked at all the time!!

Yea back when I was on P's i swear the P stood for please pull me over
If a cop just poped the bonnet and had a look surely they wouldnt notice
A12s and A14s look so similar other than the stamping.
If your on Ps east coast and pulled over do they actually check engine numbers?

Can do depending on the copper and situation...
If you're just pulled over I would think not but theyre cracking down on hoon laws. Sydney policmen set up a wharehouse less than 1km down the road from a number plate recognition and booze bus which all modded cars or cars that failed some ie. Bald tyres, too loud etc. They would be police escorted to the warehouse and checked further including full engine chassis number checks, rego license. I THINK they may of even had a full car jack so they could do walk overs of the cars. Lot of money would've gone into that operation.
