I figure it won't be long before LS will be the majority in these cars. Nothing exactly wrong with it but one of the reasons that I enjoy my firebird, instead of owning a Chevy like everyone else, is because it's something different. A stock Pontiac motor can be as reliable as anything else if done properly. Probably won't ever get the fuel efficiency or economically as with an updated OD Trans but eventually it will be seen as vintage. JMHO.
