4/7 swap in firing order..

4-7 is worth 10 hp in a Chev circle track engine...definatly sounds different...sounds like a ford.
Haven't bothered to grind up a couple of RB cams to see how the chry eng responds to a direct compairson...
I have a 4-7 in my 830 hp low deck...nothing surprising jumped off the page that I would attribute to a 4-7 swap.
