I agree with Kevin ..... I too run a quickfuel carb and love it!
I built a healthy 451" that loves to rev, with all the aluminum bolt ons . What does a 6.1 new Gen Hemi weight? I don't think they are a lightweight? I have a OD transmission and get 17 MPG on the hwy cruising. I kind of like the " K.I.S.S. method? the new stuff is great but relies too much on electronics IMO . I'm no electronics engineer so that turns me off somewhat. I like simple and being able to fix most things easily . Another negative for me is around here emissions " police" require all the smog parts and to meet the standards emission wise of the new stuff. Not so with the old. I don't make the rules.... just have to live by them....
