|NXSLT1||The stock CR sucks for boost not to mention the cast pistons, they won't take much abuse before they try to burn up. I'm gonna find out how good they are in a couple weeks.|

|sleepyTA||10.4:1-10.5:1 is pretty close. I can tell you from experience that Superchargering and LT1s do not like to go together. Nitrous is a better bet on a stock LT1.|

|Grims||I thought it was 10.5:1?|

Naturally aspriated, maybe, but 600hp will create other problems too. Stock compression is 10.4:1.
If you were talking about a blower or nitrous car, I'd say you are nuts. But naturally aspirated, its not the compression ratio that you need to worry about. Its the 600hp on the stock bottom end and pistons.
You need to plan a full bottom end upgrade to safely run 600hp.

LT1 compression ratio...
is the 10.4:1 a boost friendly compression ratio? i plan to run around 400RWHP for now and 600RWHP after building the block and getting a 12 bolt. i was wondering if head porting is needed?
