Lsa build help
 

What's up guys. I know if this the right place for the thread most of you guys seem very knowledgeable about this engine but I want to build a lsa or similar for my chevelle. I want about 800-850hp. My plans is to build the engine to get into the high 600hp range and as nitrous for the rest. Hopefully I can accomplish this by running low boost. What are some options I can look into for my goal? Thanks in advance

Iron 6.0, forge the bottom end and blow it, you're able to put more PSI through it, cheaper to build and get your HP goals easier and the iron block will last longer, easy to find a good 6.0 iron block too.

I you follow this guy in you tube be basically did you what you want. Agree with above migh be cheaper to do the 6.0 iron. I went built LSA for my first gen Camaro based on a lower HP goal.

Thank you guys for the replies. Correct me if I'm wrong. There's no real reason to go with the 6.2 over the 6.0 besides weight savings..Correct? What mods will I have to do to the engine and blower for my goal

Correct

Also not knocking the LSA, but learned and saw first hand how the cylinders barrel out in the center from boost as where the iron block retain the shape better.

I think it migh be cheaper to do the 6.0 iron.
