Quote: It's a pretty large port. I'd be willing to bet it'll hurt low speed TQ over the early casting. But with a higher rpm range, and good compression the late head should be much better!
it's gotta be all relative, as my '11 charger R/T doesn't feel like it's soft on the low end, even with 28.6" tires, 2.65 rear and 3.59 1st gear (so, equivalant first gear as a 727 with 3.8 rear gears and a 28" tire, or 3.66's and 27" tire)
Thats because the VCT helps on that. however most guys will lock out the VCT when doing a swap because their is no after support yet for that.
