That's excellent info, thanks!
Question is how to get there in easiest and cheapest way? If it gets too costly I can use the 6.1 Hemi I have sitting, haven't decided what to do with it yet. Also have an A518 46RH I could use but if I start with that swap I'm afraid money and first of all time will set me back.
Would be more fun (and faster) to build on a 340!
