Converting LA 360 to roller cam

That is the thing with injection, you dont need tons of duration. With a quick ramp roller cam and lots of intake speed you can use higher lift to your advantage when used in conjunction with a shot of fuel right into port timed for valve opening. You will get more power than with a standard flat tappet hydraulic cam gradually opening, trying to keep fuel suspended while in intake. Just look at the difference between the lobes of a FTH vs roller, FTH opens up slowly and isnt open all the way for long, while roller opens all the way super quickly and stays at max lift a lot longer. Non roller MPFI Engines are not very common
