i enjoyed the comparison,especially the big block,very impressive,with iron heads and flat tappet cam to boot.just wondering what the thought process was when you used a tunnel ram on the 422 with heads that were imho a restriction.your gen1 408 buildup a few mths ago made more power and torque with a single 4 bbl and a hydraulic roller cam.just wondering........thx  

i agree a set of rhs 235 heads perhaps
and cheaper too  

i was thinking the same thing.better yet,use the cnc'd Darts off the 408,just saved a bunch of coin,and pick up ponies at the same time........
