Thanks for the replies guys! I was leaning towards the Scats, but just wanted a little reassurance from the gang that I was going in the right direction.
It's a new build so not really changing, just getting the pieces together. I want to try and get something together this summer, and here's the short/long of it.
I have a 72 340 Duster I was planning on selling with the original block. It's been machined and is about ready to be assembled. I also have a "fresh 10 years ago" 340 that I have never run. It has the old TRW pistons so I can't run my eddy's on it. So the plan was to pull the rotating assembly out of the "new/old" short block on the stand and put it into the numbers 72 block for the duster with a set of X heads that I have "new" and ready to go. The other block can then get the set of SRP pistons, Scat rods, and the eddie heads to go into the 68 Cuda thats just been sitting in the driveway.
I know it kind of sounds roundabout, but this way I can get engines in two cars. A close to stock one for the Duster and a slightly built one for the Cuda.
