What is the difference between these two tpi engines that the auto has 195 hp and the manual has 220 stock? Also what would need to be done to get the manual trans 305 to 275-300 hp and it still be an everyday car..if this is possible..

 

LB9 manual had a more aggressive camshaft, I believe. As far as making 300 hp, you're either going to need very deep pockets or a 350 to swap in... in which case you'll need deep pockets anyway.
