Default hello i'm newbie here
I'd like to introduce myself to the forum. I'm from Buenos Aires, Argentina.
I don't have a boat. I have a few muscle cars with V8 engines. I'm looking for information on how to upgrade V8 engines, especially to get a lot of torque... something marine engines are specialized in.
Right now I want to get more torque from my BBC 454 engine for my 68 Chevelle

Do you know the rear axle ratio ?

What are the current specs of the engine?
