There is big difference between that 2barrel 305 cam and 4bbl 305 cam...
about 20 degrees difference... I'm not saying that cam is the best for a 2bbl 305 but I do know that it is about 20* short on duration for a 4bbl. 305 stocker..
lift with stock rockers and high spring pressure you have to add a little lift to get to spec but that may be a little too much for 357/390
$100.00 is a good deal though for someone it would work for....
give Bullet a call and they will grind you a brand new cam for your car... probably $200-250 range
