Well the production wise yes but until we know the full scope of how much power we can squeeze out of the new LTx engines the LSx stuff will still be the way to go for big power and/or tailored power deliver.
One thing to note, this engine has come a long way. There has been some bumps along the road but overall its a nasty lil sbc.
To start the conversation off... 600rwhp n/a on pump gas should be fun in a car that is 100lbs. lighter than a camaro ss.
