The cost of a hydraulic roller cam has dropped down to the point that running a flat tappet cam doesn't make sense to me, A roller cam will allow you better performance all around, idle, vacume and acceleration. Their is also no break in on the cam and no need for special lubricants, all modern engines run roller cams, their is no comparison on longevity, reliability and power options

So what would be a good roller cam ? Right now i am will most likely buy the Crane 284-H12 camshaft. get some 70 closed chamber heads and
a D-90006 thanks for all the help

It's the one that you want. The original application is for the '72HO Cleveland. It is also the over the counter service part for the '71 Boss 351. That one has an engineering number on it of D1ZX.

The two are for all intents and purposes the same. The D2 isn't as valuable as the D1 since when you restore a car, in this case a '71 Boss 351, you want what was installed on the car when built, which would have been the D1ZX balancer.

Both of my Boss balancers have been the D2ZX.

The only thing that you want to consider is whether or not you should have it rebuilt by a balancer specialist. The consideration is that really valuable/desirable parts, like this, HAVE been "lost"...somewhere, so make sure you make it a point that you want this thing back, not a substitute.

There are a bunch of people that are going to tell you that yours is junk, that you want the ATI, then ask you if you want to sell it. Wink

It's also the one, more likely than not, that the factory race teams would have used on the Pantera back in '72. So that kind of adds desireablity to a Pantera owner. Unless you feel the right thing to do is cut the car up and stick a Corvette engine it it? There are those around too? Big Grin

This could be one of their Panteras?

The spec's of the right cam, is all about you, that said all the major cam manufactures now offer a complete spectrum of grinds, from mild to wild, but the power options you are interested in can be calculated by the specialist at the tech center, every cam maker has a tech center and will be glad to offer their help to you, they don't charge for their advise, get a couple of opinions, Crane, Comp, Lunati,Isky, etc.
