SFfiredog Hi Mike. I have heard that thiers lifter are great. Some of the bracket 5.0 mustang racers got caught using them. 2 problems that I was told and shown was they are harder than the cam shafts and they cause more heat and friction because of the force on the edge needed to be moved. The lifter we are talking about are flat style not the V-shape like TXF. TXF make the same claim to using a roller cam without roller bearing lifters. I know it is a long ride but I would like to see your car at the Run&GUN in Oct. You could caravan with some of the people out there. I drive solo and its 16 1/2 hours from N.J. to St Lious. It has rained every year I have drove out there. Are the motors you are using have roller bearings for the cam? I was told that a couple of people are using big block chevy roller lifters in there motors because the roller bearings are bigger. Do you bushing your lifter bores? Got to go.
