I have both set ups right now.. normally
I would run a roller but I went with a SFT
a couple of months back so I could run less
spring pressure.. I have the EDM hole in both
set ups.. the reason I did go with the SFT
was because the injection didnt like the roller
set up... but I'm finding out it really wasnt
the cam that was the issue... I think if you
were to look back you might find that SFT cams
fail far more often than roller cams.. so far
I have not had a roller cam/lifters fail in over
20 years of running a roller cam...I will see how
it goes with the SFT
