anyone know what it takes to convert a flat tappet 351W to hydraulic roller??? i know someone recomended it to me and i was wondering how much it would cost

 

At minimum, the cost of a new roller cam and roller lifters and new pushrods the correct length and I think, but I'm not sure, you need to have the block machined to fit the roller lifters too, but I'm not absolutely positive about this part. You could probably contact Comp Cams and they could tell you exactly though!

 

Just a ball park figure, I guessing between $500-800
