I have had 2 engines done in the past 1st was my GX with rings pistions (1st oversize)bearings,cam reground,welch plugs all seals,oil pump checked,full gasket kit,complete head job and manifold faced and a new timing chain,cost was 900 bucks cash.
second was a std a12 had rings bearings all gaskets and seals head fully recoed I cant remember if he did the timing chain but was a nice tight motor when started and ran like a dream cost was 500 bucks cash.
All I can recommend is shop around to all the engine shops and have a full list of what you want and dont just go to the big well known shops but the smaller guys ( as I did) do a good job.

^^ oops.
I paid 1/2 of the price of my LPG kit to get it shipped from the UK. ouch! especially shipping an empty LPG tank, that thing was heavy!

I had an a12 rebuilt for $2500 and a set of 40 doce webbers and a manifold over from england brand new for another $2500. I didnt relize there would be some much tax on the import and had to use a broker to get it here. But it goes well about 45kwatts at the wheels and goes up to 9krpm no worries

i just payed $2,500 for my full rebuild and recondition of my A15. New everything, they took out the engine and did their thing then put it all back in and i get a full 3 year warranty
oversized pistons and double spring valves, very good, goes very hard.

you do get what you pay for sometimes.

I feel my $1500 was "high" but the engine was good as new, fired up ran fine, doesn't leak or smoke, got over 10,000 miles on it now, close to 8,000 on LPG and it's as good as new.

they put a cam in it and it may have a few other tweaks.

this is far superior to the many $400 used and abused japanese engines i was talked in to, many of which never made it to 3000 miles.

if you do the work yourself, then you can spend every penny on better quality stuff.

I pay people to do things like clutches and engine installs because i'm lazy and don't feel up to that stuff yet.

i saw a reco 1200 motor at BnB in mildura a few years back for $700 changeover

thanks guys

If you include your basic location in your profile, you just might get a recomendation for someone near you.

If your engine needs just a major overhaul, then any reputable repairer should be able to provide a quote.

If your engine needs reconditioning, then the number of reconditioners in your area may limit your choices, but once again, you would need to get a quote from at least one of them to get some idea of what you are up for.

Boring $120
Pistons $270
Bearings $120+
Gaskets $120

Just a assessment on some of the stuff so $800 easy.

I mean get it done professionaly I think the engine needs rings, pistons etc
