3v Aluminum Block vs Iron

Doing an engine build and already bought a spare 3v motor. Would I be better off selling it and buying an iron block? Doing an engine build semi-soon and don't wanna run into any issues. Gonna make 700+ wheel. Am I ever gonna have to worry about it, or do I just need to buy an iron block?

Block will be fine. Just make sure you have strong enough internals.

Pick your poison.

A stock block is good to north of 1000. A sleeved teskid block or a boss iron block is a step up from the 3 valve block but isn't needed for 700rwhp. Im around 1000rwhp with the stock block.
