Ford Racing's hydraulic roller lifters feature the same high quality as the pieces that Ford uses as original equipment in the 5.0L HO EFI engine. Some are direct replacements for the OE lifters and are 50-state legal. Others are designed to be used when converting a "non-roller" block to a roller cam. Note that custom pushrods and minor clearancing work to the block may be necessary with these lifters.
Do these work if I’m using a small base circle cam in a no roller block setup with a spider and dog bones?
