Quote: I am using stock non MDS lifters that are gutted and had a solid roller grind cam made for it.
Also I do have the Harland Sharps that are not cheap
Alex The FAST XFI is great now that the motor is happy. I had so many issues with the HYD roller cam and non ADJ rockers valve springs push rods etc... that I had motor issues not EFI tunning issues like I first thought.
Good to hear, what magic is there in your lifters?
