Chevy/Olds aluminum block

[Chevy454]

Could be used on the street, no problem...it'll only be as racey as you build it! LOL!! Only issues I can think of are if it's a tall block, then you'll need special headers, intake (or spacers), distributor...everything else sounds standard fare big block stuff. With that block, you could easily go big bore/stroke (550"-600" I'd say), but keep the compression down to pump gas levels, and have a thumper of a street engine...

Thanks Rob, that´s what I wanted to hear ! I think I can buy a couple of Dart heads that would fit. Then we would need a proper superchargerintake and some spacers like you said.

That looks like a dry block to me and not very streetable. I think these things are super exotic and there's a reason that you don't see them used in fast street cars. Do some more research.

You know what, you may be right, Mark! In the first picture, there are holes for the water pump flow, though, but none on the deck faces of the block? Maybe it's for use with dry heads, and just circulates coolant in the block itself somehow? Wierd...

[COPO_Anders]

Yes that´s weird. I think I´ll contact the Keith Black company and ask them of their opinion.
I spoke to a guy a couple of years ago, who used an aluminum K.B. Hemi raceblock on the street. He told me that it worked if you knew which measures to take.

"Don't quote me", I remember seeing a blown one at the track with a few water lines off the top. </font>

Anders, IF it's a "water block" you might be able to. But most of these KB block don't hold water too well. That's the main reason you don't see many on the streets. Once they heat cycle and things move, it leaks all the time. That's why most are "track only" deals. You would be far better of selling that block and using the new Dart or Brodix.
