Lsx questions.
It's time to build a new motor. Current set up is a bbc 474.
Looking to step into the new century. My class rules state no power adders, no fuel injection and not to exceed 474ci. Class currently doesn't allow for aluminum heads. So I need 474ci iron head and plenty of HP.. Please fire away with suggestions..

Agreed with the guy above this is not a class for a LS engine as the only cast iron heads for a LS (to my knowledge) were the very early 6.0 cathedral type which will limit hp significantly on any big CID engine.
BBC have plenty of good offerings. You need help refining your BBC not a move to LS.

Yeah that iron head part kind of screws it.
There was only a single iron casting ever offered for the LS in 1999-early 2000 and it wasn't a good one.
The class seems like its geared more towards being a nostalgia class.

Yes their excuse is they want to keep it competitive and cost effective to build.

So what is a realistic number for a lsx in the 474 ci range? No turbos or nitrous with a good set of heads.

If you're forced to run carb, iron heads, etc, it would be better to stay with the big block.
