this is where I find things odd...mopar lists it for both, so does 440source (seems like a copycat flywheel) and american powertrain lists theirs for both as well. But then the diagrams in the mopar books that you posted show them as different.Unless there is another bolt on weight that I didnt get that is for smallblocks, then im confused as to what to do. Almost seems like false advertising on more than one companies part lol

The engine is already together so i can't really go balancing it as an assembly. Low budget stock bottom end 360LA with a summit stock replacement external balancer and this flywheel. I was hoping the weight 440source provided would be enough since thats what they told me to.


has anybody else besides me and 440newport used or thought of using this flywheel in a cast crank 360 application???
