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.




Spring pressures collapsing the lifters making it run poorly? Mine seems to do that for a few minutes
