280 H is a great cam ,slightly rough idle but great power .
Now ,ford has 2 different firing orders for this cam ,it interchanges with the 351 and that firing order is different
The 351 order is 13726548
The 289 302 is 15426378 .
They both work in both motors but you have to know the firing order of the cam in use . Simply try both fireing orders if you do not know what cam it is ,you will know if it is the wrong fire order
