I've tracked down a block to put into my '66 122. (As you may recall in an earlier thread, the engine threw a rod.) This engine came out of a '75 240.

I wanted to get the opinion of others here about what cam(s) I should consider in this "new" engine. The b-20 that was in the car had the ipd street performance / isky cam.

I always really appreciated the extra guts the car had in the mid to upper RPM range, but was never really happy with the rough idle, the fuel consumption, or the (relatively) low power output from a dead stop. The rough idle also caused the engine to vibrate quite a bit more than I'd like.

There has to be a happy medium somewhere in-between (with a lean towards the performance side of the spectrum.)

Any opinions on which cam to keep an eye out for? I was thinking an early D grind would be a good choice but I'm not sure how it would compare to the isky cam I had before. Are there any options other options worth considering?

In regards to the D cam, is there an easy way to identify the difference between an early D and a later one?

Thanks as always.
