Lets see, race car compared to street car, kind of an apple and oranges thing don't you think. W5's? It better run 10's.
If you want to compare apples to apples lets do it. I unbolted all the parts from my J headed 360 and installed them on a street 408. Installed in the same car and it picked up 6 tenths. Worth it? certainly.
Bottom line, no one said the 360 crank wasn't good, in fact it is awesome. I'm just saying to the anti eagle crowd there is nothing wrong with the 4" Eagle cast crank if used as recommended..
