Here's a little more info on this N-P Hemi; the heads were designed by Frank and Scott, cast and then approved by NHRA to run in Comp. Scott will drive it in Jon Rowly's N&P car, at 1'st in B/ND, and then increase the injector size to run A/ND. They did allot of work on the 354 Hemi block, like bored out all the cylinders into the water jackets and welded in larger bore sleeves, because they want to run a bore and stroke like their 14° SBC. Also built main bearing supports, and more work in the lifter casting to run a larger lift cam. And I'm sure allot more I don't know about. I guess the next step is dyno tests. The N&P heads flow a ton, I think Frank said over 450cfm.
This will be an INTERESTING combo !
