メモ的な感じなので各自でわいわいして

使用するものは、ブロックに視点を合わせた時に表示される線が描写される直前に発生するDrawBlockHighlightEventです。
後はmodding wikiでEventの使い方を見つつ、適当にわいわいします。

とりあえず、クラス作る

public class DrawBlockHighlightEventHooks
{
    @ForgeSubscribe
    public void onDrawBlockHighlight(DrawBlockHighlightEvent event)
    {
        EntityPlayer player = event.player;
        ItemStack itemstack = event.currentItem;
        MovingObjectPosition target = event.target;

        if(player == null)
        {
        	return;
        }

        if(itemstack == null)
        {
        	return;
        }

        if(!(Item.itemsList[itemstack.itemID] instanceof ItemBlock))
        {
        	return;
        }

        if(target.typeOfHit != EnumMovingObjectType.TILE)
        {
        	return;
        }

        GL11.glEnable(GL11.GL_BLEND);
        GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
        GL11.glColor4f(0.0F, 0.0F, 0.0F, 0.4F);
        GL11.glLineWidth(2.0F);
        GL11.glDisable(GL11.GL_TEXTURE_2D);
        GL11.glDepthMask(false);
        float f1 = 0.002F;

    	double x = target.blockX;
    	double y = target.blockY;
    	double z = target.blockZ;

        int blockID = player.worldObj.getBlockId(target.blockX, target.blockY, target.blockZ);
        Block block = Block.blocksList[blockID];

        if(block.isBlockReplaceable(player.worldObj, target.blockX, target.blockY, target.blockZ))
        {
            //上書き設置できるブロックの選択範囲は描写させない
            event.setCanceled(true);
        }
        else
        {
        	ForgeDirection offset = ForgeDirection.getOrientation(target.sideHit);
        	x += offset.offsetX;
        	y += offset.offsetY;
        	z += offset.offsetZ;
        }


        double d0 = player.lastTickPosX + (player.posX - player.lastTickPosX) * (double)event.partialTicks;
        double d1 = player.lastTickPosY + (player.posY - player.lastTickPosY) * (double)event.partialTicks;
        double d2 = player.lastTickPosZ + (player.posZ - player.lastTickPosZ) * (double)event.partialTicks;

        AxisAlignedBB axisAlignedBB =  AxisAlignedBB.getAABBPool().getAABB(x, y, z, x + 1.0D, y + 1.0D, z + 1.0D);
        axisAlignedBB = axisAlignedBB.expand((double)f1, (double)f1, (double)f1).getOffsetBoundingBox(-d0, -d1, -d2);
        this.drawOutlinedBoundingBox(axisAlignedBB);


        GL11.glDepthMask(true);
        GL11.glEnable(GL11.GL_TEXTURE_2D);
        GL11.glDisable(GL11.GL_BLEND);
    }

    private void drawOutlinedBoundingBox(AxisAlignedBB par1AxisAlignedBB)
    {
        Tessellator tessellator = Tessellator.instance;


        //下っぽい
        tessellator.startDrawing(3);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.minY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.minY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.minY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.minY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.minY, par1AxisAlignedBB.minZ);
        tessellator.draw();

        //上かもしれない
        tessellator.startDrawing(3);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.minZ);
        tessellator.draw();

        //側面だったら良いな
        tessellator.startDrawing(1);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.minY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.minY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.minZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.minY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.maxX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.minY, par1AxisAlignedBB.maxZ);
        tessellator.addVertex(par1AxisAlignedBB.minX, par1AxisAlignedBB.maxY, par1AxisAlignedBB.maxZ);
        tessellator.draw();
    }
}

そして、わいわいしたクラスを登録して終了。

MinecraftForge.EVENT_BUS.register(new DrawBlockHighlightEventHooks());
