I have just put in a L31 r crate motor to replace my blown up 350 in my 98 Sierra. It is made as a direct replacement. My question is does anyone have a sheet on the ratings for this motor? I read in another forum when they started making these motors they where rated as a replacement with 330 hp but i dont think this is right! when the old one was at 255 hp. Any info would help thanks
