The current engine is a 466BB with a Crane Cams 359351 hydraulic roller. Not a bad cam, but I want something with a little more lope to it. Spec's on the Crane cam is .590/.614 lift, 228/238 duration.
The hydraulic flat tappet cam that comes with the 514 seems pretty nice, but I would really like a hydraulic roller. Has anyone replaced there stock cam with a roller a hydraulic roller?
Any input will be appreciated.
Thanks

There's really no performance advantage to a hyd roller and as long as you use the proper
oil with the flat tappet it'll actually be more durable than a roller. If you want something with more lope at idle you'd be just as well off going to a different flat tappet cam.
