Mostly u can shave, mill and grind a lot of iron metal out a stock or even aftermarket block. Just google for yourself.
Ok for block weights i had to answer my own question on that one as its right from the GMPP catalog.
Production iron 350 blocks, 383 = 181lbs
Siameze Bowtie iron blocks = 196-208lbs
Bowtie aluminum 350 blocks = 90lbs, 400 aluminum blocks = 89lbs or 101lbs.
So the aluminum block is a 90lb weight saving but shaving, milling and grinding will take a big chunck out that 90lbs.

Hi guys. My engine just let go. I'm ready to do an alloy small block. Does anyone sell an aluminum short block. There is an alloy crate engine for sale, but I have good AFR heads, air gap intake, and Holley Fuel injection, so all I need is a short block. I don't really care about displacement, but I would like the 100 lbs weight saving. There was someone out of LA that makes and sell alloy small blocks at SEMA, but I really would like an already assembled and balanced short block.

They built a 427 long motor for me based on a BMP (world) alloy block. Good price and service
I only wanted the a long motor as I'm using my existing fuel injection etc. I guess they would do a short motor as well.

You could try Nyes Racing Engines in Muncie Indiana.

Hot Damn! Unless you guys think otherwise I'm going to take a chance and put $1000 down for a machined block. I have no problem with "Chinese" parts. It is World Products, I think a reputable company. I really wanted a complete short block. Maybe someone here, in Cali. hopefully, will be willing to assemble one for me. Gkul, my brother from another mother. Want to build an alloy 427?

Generally you get what you pay for.
You can buy a pair of assembled, aluminum 200 CC heads that have 64 CC chambers, straight plugs, set up for flat tappet cam for $615 delivered to your door.

Is one set with the same exact description worth 256% more than the other set??? Ask me when your pulling your $8-10,000 engine because it dropped a valve and took out everything.

Keep us posted, is it setup for the more modern roller cams? Be interesting to get an alum 400-427 for what a dart based iron one would cost.

That is true but you have Brodix, Dart, World, BMP, Rodeck, Donovan and General Motors all making a SBC Aluminum block and they are all $4500 and up. Base prices are bunched pretty close, the more options or deviation from base the more the price goes up. Then you have this one, single manufacturer that is unnamed in the ad and remains unnamed that is selling a SBC Aluminum block for under 1/2 the price of EVERYONE else plus covering the shipping from Australia and California on top of that. Pro Comp used to claim Australia as the point of origin as well. Minimum Wage in Australia is $15 an hour and raw materials are imported. Do you understand why this don't add up??? I would not be the guinea pig with a $10,000 build, that is just me. Don't you have AFR heads? If so, think back, why did you buy them for twice the cost?

Thanks for that. I emailed him and he called me back. The blocks are made in Australia, essentially a Dart replica. 1 year warranty if they do the machining. They also sell reciprocating parts. They can build me a 427 short block. They don't take credit cards, pay pal only. Stay tuned.

I pretty much call BS! on the statement they are made in OZ. Get the brand name and I'll have Aussie John check on that one. They dont do child slave labor in OZ and their wage rate isn't that far below the USA. It was once said the aluminum small block heads were from OZ too but, now we know better.

Then I remembered a few years back Procomp (now Speedmaster) was making knock off Dart Blocks cheap. Here is a link on some feedback on them.
http://www.dartheads.com/dartboard/s...?t=1512&page=2
And some metallurgy testing.
http://www.yellowbullet.com/forum/sh...d.php?t=181302
Figure if they bought a new name recently, knocked off a tested inferior block in Iron then recently came out with another knockoff copy in Aluminum I would first question the metallurgy of the block itself, second the Alloy, third the casting integrity, fourth the metallurgy and fit and finish of the main caps and cylinder sleaves and fifth the machining and tolerances throughout, lifter bore locations and size, cylinder centerlines, oiling passages and routing, cooling passages, routing locations, capability of the aluminum threads to hold fasteners at full torque.
I would stay away, far, far away. Way to many red flags and possible issues for me to chance a $10,000 + build..

I have always known Speedmaster products as being Chinese knockoffs. I'm in Australia and I wouldn't buy one!!!BTW the minimum wage in Australia in pretty much double that of the US.

The Australian Council of Trade Unions called for the 71c an hour increase as it issued a dramatic warning about the need to prevent the formation of a "US-style underclass of working poor".
The national minimum wage stands at $622.20 a week, or $16.37 an hour, and is reviewed annually.
