Been thinking about this deal and the comparisons made.......Jason, would you post average data from 6800 to 8200. I believe that even though "peak" numbers are similar (mine made 739 at 8200).......where your combo will shine, with the heads, is in the average numbers.
For the sake of comparison, this is a non RR Dart Pro 1........2.8" MCSA 2.080 valve, that flows right around 350cfm at .900lift. Cam is 272/286 .866/.848 lift. BBC core...... .842 lifter. 7/16 pushrod, 1.65pivot/1.85 ratio stainless rocker, with Ti valves. 11.7:1 compresion, Dart SHP block (nothing exotic) Magnum XL, with Promod rods. Single plane Eddy manifold with a single dominator. 11,000 miles and it is in for a freshen. 2 Drag Weeks.....a 2nd and a 1st. Been a best of 9.71 at 136 and change.......at 3600lbs in my Chevelle.
