Take a look at ultrastreet.net for engine options. They have plenty of 500-650hp ford racing street motors. EFI is an option on any of their engines and an aluminum block is available.
I have the SBC 427 8 stack motor and am very happy with it. The engine was tuned and dyno'd before shipping and it was an easy installation and started right up. The engine will go back under the knife for 700hp, lol.
Most peoples "issues" with 8 stacks have much more to do with understanding how to get the butterflies equalized - than they do with "fueling" issues. The fueling issues come about as a result of not understanding how quickly these respond to throttle. So typically they're lean.
If your in Europe and do not HAVE to buy from an engine builder in the USA check out Richmond engines www.richmondengines.com (not much of a web site but he is a WICKED engine builder) he builds lots od Sprint car and boat racing stuff last time I was there their were 15 SBC stack injected engines in for a refresh. I have had 10-12 engines done by Jim that others had messed up and to date have NOT had any problems with them (not all mine mostly customers engines) Jim will talk your ear off, you will pat a bit more but that is because NO corners are cut. great guy, Honest will not screw anyone. super busy because it it.......... and knows how to ship worldwide.
