I know its a link to an ebay link but thought it was mega interesting for a discussion point

http://www.aussiemagna.com/forums/showpost.php?p=1095497&postcount=1487

What could be done with an engine block like this? Would it suit a high power turbo application with those sort of specs?

If it really is what the dude says it is, then $1000 for a $30,000 block is quite a bargain I would have thought?

===============
The blocks are an extra heavy duty casting, with 4 bolt mains with a 1 piece main bearing cradle and thicker cylinder walls than a standard block. There was only 40 of these ever cast, at an expense of $1.2 million dollars (AUS, so $30,000 each!!!)
===============

I want to know who this guy is and why he is flogging them off?

If these are genuine blocks these may be awsome for people like Jasonsvrx and crew who are building big HP motors.

I dont thnk there would be much worth for the every day car due to the fact that you have to then get all the other parts to put this sucker together unless of course you have a sc setup or again you are looking to build a serious street engine

Jasonsvrx, zero or similar should be able to confirm if these blocks actually existed and once confirmed may be a good pick up if only to put it away for a rainy day

Well, you could buy it and fill it with the most expensive components you can find, then put it in a roadcar and go from 0 to 60 a bit faster than anyone else, and you'd have some major street cred and bragging rights!

A waste of money, unless you want to build a Pajero for the Paris to Dakar rally.

It's your money and if you want it and have big plans for it, get it - your decision, at the end of the day.

unless you were to bore it out i wouldnt bother.

the dollars and time worth putting it together, finding the parts etc etc, wouldnt be worth it.

Stop being so short-sighted! Why are any of us here if thats the kind of attitude AMC-er's have? It would complement some of the other more extravagant builds as Mal said above. Stick it in an AWD-build and the thing would be an animal

Just like to inform all members that these blocks were the pilot run of blocks cast and fully machined at MMAL. There were two block casting in the 6G75/380 development, the later (production) was called a thickwall refering to the bore thickness. All 380's use this block it is not special at all. Save your money people and buy a complete engine if your looking for a 6G75.

Cheers Dave.

Sorry guys, but I am 100% with Cybermonkey. IF this is a real item and not just some sort of scam, it would be an oppertunity to build something different

Look at what a lot of people have spent on std blocks by the time they have sourced all of the forged rods etc etc and here is an oppertunity to have a BRAND new block, regardless of if it is a super 30grand block to build an awsome 3.8 motor, not something out of a wreck

I also agree that there is a very narrow minded attitude towards people here trying something different. Who gives a stuff if it does not work, at least they try and perhaps come up with something else in the process

Starting price is $500 bucks, while I would not pay a grand for it, if someone gets it for close to that starting price may be a decent pick up

Guys, there is more to life than parras and clear side markers



****edit, seeing DaveTJ's post stating that ALL 380's had this block, looks like a std new motor form the warehouse would acheive the same thing

Yeah i was just about to post that up too Dave. As i was told that all the production 380 blocks were thickwall castings so i thought the Ebay guy was pulling his you know what lol.

Ive actually just sent him a friendly email asking more about these blocks etc.

Jason, when or if you get a response, can you post up here, will be curious to see his explaination

Yeah will do. I made out i didnt really know much about the G74/75 series of engines, so hopefully he will respond

Unless he's following this thread :)

Is there 4L+ capacity in that block?

Bored and stroked, it is possible (been done in US) with custom rods and pistons.

Yeah, been over that data to death. Should be able to 'borrow' a rod from another motor and since custom pistons are on order anyways... Or chase some Chev components then bore and machine crank to suit. Cheaper. Actually an interesting idea.

Talking to Rod C. one day and he said after checking out sliced up 'test' 6g75's at MMAL that it should be safe to bore to 4lt. There's off the shelf GM pistons that can be used.

Anything is possible but if you were running a boosted setup, you would wanna keep as much "meat" in the bores as possible for ultimate strength with big amounts of boost.

All the engines ive built ive never bored them anymore than first oversize (0.5mm) just to be safe.

If you put a stock 6G75 into any of the magna models would it just bolt in? and also would it make a big difference? What would you need to get something like that done?

Search! fella.

Search! fella.

Of Course :P

Out of interest Dave how thick were are the walls in 6G74 and 6G75 blocks? I understand the last pre-diesel Dakar engines were 97mm bore. Does anyone know for sure?

I checked this guy out. Not very impressed with his eBay claims and response in light of Dave's knowledge about these blocks. His name is Glen.

Alan,

At least you seem to have got a reply, I emailed him with some genuine questions (but i made out i knew nothing about the blocks. If that makes sense) and he hasnt replied.

His buy-it-now price has dropped to $750. He says they are unique, never to be made again, so you better grab 2 if you are serious!

May I point out:
(1) They were special, because they were the first. They made many more since then, so they are not unique.
(2) There is a Mitsu foundry churning out more of these blocks even as we speak.
(3) A block by itself does not make mega horsepower, its the internal bits.
(4) Serious engine builders prefer to rebore and reface a used block rather than using a brand new one. Stress relief in the metal of a used block through use and many hot/cold cycles make it more reliable than a new untried block.

Youve been reading the old F1 BMW turbo history havn't you - those early 80's F1 1500 HP turbo engines used old 2.0 litre street blocks from BMW 2002 models that had done well over 100,000 Km. The old BMW 2002 still makes an awesome track machine able to humiliate much newer machines. Weight to power rules! Pity I have an AWD Magna now but my old '82 E21 323i and '86 M535i still boogie.

How's the reliability/Cost of Ownership on this been?

Nah! Using an old block for a performance build is an old trick, dates back waaaay earlier.
