I wanted to convert my 289 hydraulic lifter to a roller lifter engine. I am going to get a roller cam that has a matching profile to what I have now (non performance; this is a daily driver car) and I want to know what lifters I can buy that will keep me from having to machine the top of the block. Basically I want something I can drop in and not have to take the engine out of the car.
