Aluminum slant block
SLeeve it. We did that to a Vega block back in 73 at tech school. We surfaced the deck and put it together it worked perfect.
The problem is, the Al Slanty has 6 free-standing cylinders, and are already cast with iron liners. A Civic has 4-in-a-row free standing, but siamesed, they tend to grow & crush the gasket near the middle..& the head bolts have to be checked carefully, even taking .010" off the head can cause the threads to bottom in the block.
If You're familiar with the Dan Wesson revolver, You know the point of holding the cylinder(barrel in that instance) in tension under pressure, instead of free standing. In the firearm, the difference was small, but they are by design much more rigid than a production engine block. In the barrel, it is held around it's circumference by a barrel-nut, head bolts cause points of distortion at-deck.
So there are trade-offs both ways here. But Al Slantys are unstable by nature either(both) way(s). They were to be a light-weight, reasonable output, economy power plant...not a racing piece. If coolant was maintained, & modern head gaskets are used, they should service fine.
