The guys with Edelbrocks will tell you they are the best, the guys with EQ will tell you they are the best. Weight aside, OOTB they will be hard to tell a difference in performance. For your currently outfitted engine, I would say EQ because there doesnt seem to be much difference until you get over 500 HP and they are less expensive. If 45# is a concern, put battery in trunk. The first question I would consider from anyone giving advise is how many pairs of EITHER have they installed, driven or even touched. If they only have had one pair and trash the other without ever even having seen them, then its just bullshit they heard on line.
There are advantages to both, it just depends on which brand/type gives you the most benefit for your particular situation/application.
My buddy at EQ said Brian at IMM is doing a build with EQ heads for MM mag with dyno test coming soon. If you are curious about EQ this should clear the BS up as many here think they are junk. IMM also sells and ports Edelbrock. I am interested to see how that turns out. People also respect what he says so hopefully it will clear up some unanswered questions.
If you want to know my opinion, PM or call the shop at 541-955-0363 as I have been bashed enough for praising EQ. I sell both and have installed 30+ pairs of Edelbrock and probably over 40 pairs of EQ in last 15 years. We are also cheaper than Jegs or Summit. I will share what I know regardless of who you buy from. Evan
