For NA and at that power level you should be fine. See if you can get the mtg date to confirm No issues with RHS. Perhaps a sleeved block or Dart aluminum block would be a better option if you're unable to get info on that particular block

I'd go with the Dart block.

Or the GM LSX Iron. If I had to have Aluminum I would use the CPR Blocks, larger
Bore Capable as well. I would not use the rhs Blocks too much money &
too many problems in their history.
my .02, good luck

Darton sleeved block would be most cost effective for a large bore aluminum motor...

I truly wonder how many RHS blocks had a problem vs. how many sold did not. And also under what circumstances too.

I would stay away from the CPR/LSr block. I had a real bad experience with the mfg that hasn't been resolved to date. If aluminum aftermarket is a requirement I'd stick with Dart
