We've thought about that as well, seems like a great platform for sure. I think Raylar is doing some LS stuff. I am thinking about doing an LS in my 71 Trans AM. Is this the kind of thing you do? I did an L98 TPI in my 71 Camaro several years ago when they were the latest greatest. All i can say is I'll never run a carb again.
How would you handle an 02 sensor in a marine engine? Is it still possible to get the system to function in closed/open loop without it?
