I completed the H/C/I swap about 2 months ago and am currently troubleshooting a backfire issue so I haven't had a chance to dyno yet, I won't have any numbers until problem fixed. I've seen similar combos put out 300+rwhp/320+rwtq with supporting mods e.g longtubes, 2.5" exhaust etc. I'm running Comp Cams XE270hr12 with 1.72 rr (218/224 .550/.550) @.050. I have noticed the car is "alittle soft" off idle but pulls quite hard from 2800rpm right to 6000.
