It has a Hughes roller cam with the fuel pump adapter on it.

I assume since you had to use the Hughes fuel pump adapter that the cam is a Magnum shaft- did you take into consideration the rocker ratio difference between the Magnum and the LA (1.6 vs 1.5) when you put it into your roller LA? Total lift will be a bit less than advertised.
You're probably aware, but like I said; I have to ask.
