The brand is not as important as the grind, most of the blanks all come frome the same source.
For a nice street engine that sounds cool I like the Isky or Comp 270 grind. if you're more concerned with fuel economy you need to stay stock or near stock.

Bullet Cams has both their and Ultradyne lobes which ammount to hundreds. If you call Bullet and ask for Tim he will produce a cam specific for you're particuliar wants and needs. It won't cost much if any more than a generic off the shelf cam. Another thing I like about them is most lobes are designed around Chevy or Ford lifter and base circle dimensions, they use a computerized grinder that transferes the cam to our specs. All of their cams are made to order and usually arrive in about a week. Tim worked with Harold Brookshire for 30 years, Harold (formally Ultradyne Cams) is in my opinion the foremost cam designer on the planet. He's responsible for Comp's high energy and Lunati's Voodoo profiles to name a couple.

As we discussed elsewhere, it all depends on your base engine configuration. If you are going in with the later model 401 soup dish pistons design then static and dynamic can be a lot closer that if you decide to go with higher compression pistons. Likewise, there are other things such as the squish (quench) characteristics, deck clearance and other design characteristics that will make dynamic compression more relevant.

Thanks Dan,
I have to wade through the static vs dynamic compression ratio discussion first. I'm trying to get an engine with as much bang for the buck as possible on 87 octane gas. In ND it's 75-100 miles to anywhere and gas is not going to get cheaper.

Lunati, Isky and Elgin have some real nice off the shelf AMC cams very similar to the group 19 cam. I've used the Elgin 910PK (K stands for "Kit" with both cam and lifters)many times and it is a very nice cam for a mildly built AMC.
Crower can also work with you and design a custom grind for you engine simply by your telling them what bore, stroke, compression and head flow you will have on the engine and what your desired characteristics of the cam are. I am sure Lunati and Isky will do the same. If you offer up your specs and intended use, I am sure a couple of us can give you a variety of good recommendations.

Off the shelf, I'm not smart enough for anything custom. |

So far I have not had that experience with Comp Cams but have only use their cams a handful of times on nearly 50 engines. Split Cams seem to work really well in AMCs and comp only has a couple of split profiles for our engines. Plus they are mass production and I prefer to use the guys who grind their own for a custom build. If on a budget build then it is Summit brand cams for the best bang for the buck compared to all other options.
