LS1 and LS2... small, light and lots of power does not a good engine make, not when it has 16 valves and 1 camshaft.. they're both pretty damned inefficient stonage machines imo.. If you're after something aussie with shitloads of torque, buy an FPV Tornado.. If you want power, there is a plethora of other machines out there that do the 300kw+ formula using less fuel and putting out fewer tailpipe nasties. I can't think that an engine with basic architechture dating back to the 1970's is a good engine.. Personally I would rather be able to brag about how much power my engine make AND how little fuel it does it with AND how hightech it is rather than just how much it makes.. thats just me..
