Pond HD aluminum block. I plan on running the snot outa it. Race only.
No fill ?
Half fill ?
2/3 fill ?
That be the question.

This is one of the newer Pond blocks, with the beefier main webbing, right? If so, I wouldn't fill it. One thing that is a big advantage for an aluminum block is being able to replace the sleeves. If you fill the block a damaged sleeve would have to be bored out, and I think replacing a bored out sleeve might be problematic.

Not sure of your concern here, as the only time this really would be problematic is in the instance of 'wet'-sleeves. Otherwise, other than perhaps a little less elastcity in the cylinders requiring a little more 'push' on installation and paying closer attention to the fitment. Otherwise the only real pain is the weight increase of the hole piece in handling; not so bad with aluminum blocks, but when someone brings in the cast iron, tall-deck, racing blocks filled,..............makes one wounder why I shouldn't change to the little four cylinder import stuff! ::)
And I generally, with press-in type sleeves as typically encountered, we will bore them out, as this reduces the strain on the block casting and reduces damage to the existing cylinder bores upon removal. :)
