LS1 in reverse rotation
it would probably be easier turning the motor around in whatever vehicle so that the front of the crank did the turning instead of the back.just a thought,im more curious as to why you asked the guestion though
He wants to be different. Everybody's got engines that turn clockwise, imagine what it will run going counterclockwise!
BTW, you would have to reverse the spark timing and make the starter turn the other direction to start it. And also reverse the injectors spray and the water pump and remove the tranny.
Hell leave it alone.......

I don't know if anyone remembers, but when the LS1 was in testing they did a reverse rotation test. I can't remember if it was Wyotech, or someone else... They ran the stock engine on the dyno to redline, and then reversed it which produced over 900hp from the stock LS1. I remember seeing it, but don't remember the specs......

How would turning the engine in the opposite direction gain 3 times the hp than stock. If that was true car companys would be running 2 cylinder reverse rotation 300hp 100mpg.

Why would one have to run backwards? Curious, and if its needed for physical reasons why not just have the outdrive spin the prop the other way? Why reverse the whole engine? If its just for cooling , it can be dealt with much simpler I would think.
I'm not 100% sure but im pretty sure it has to do with the torque keeping the boat from running straight. It has nothing to do with cooling. LS1'a are aluminum and you can not run an aluminum engine in salt water unless you use a heat exchanger. Reverse rotational rotation is standard in dual engine boats, see below
