You guys are really fine tuning here when comparing QC and RC models. Looking at the two the QC are what 600 pounds heavier and something like 30" longer. The longer wheel base probably makes the biggest difference. Same basic engine mods, trans and gear ratio should give very similar results with the RC having only a slight advantage. Maybe a RC with 3000 stall, 4:56 with a XFI 273 would make a good combo. The XFI still has 114 LSA. Anyone have thoughts about tuning with the SMT6 or something other than SCT or DSP?
Talk to Danniel (Kay9) he put a 273 in his rc. Its to much of a high end cam, he put in 4.88's and that wasn't enough, he also wants to put in a 3400-3600 stall. That cam is almost all top end. The 268 is more of a mid/mid-hi cam, so you still get a nice strong mid range.
