Mid 10's are easily done with iron heads. I ran a flat top piston zero deck 30 over 440 with a set of Dan Divorac Max wedge ported 452's in a 71 Scamp. Ran 6.40 1/8
I had Dan do the work on my 440, excellent guy that knows his Mopars. I`ve heard that he`s had a lot of medical issues and has had to sell one of his factory race cars to pay for hospital bills. I hope he`s gotten all of that behind him now and that he`s better healthwise and financially.
