i had a set of edelbrocks atop my 416, .585 lift ultradyne solid cam and 11.5:1comp, and i was disapointed. 11.8 was all i could muster out of it. I put a set of 1976 casting w-2 race heads with 2.08 long valves and the car went 11.5 right out of the box. this is in a 3700 lbs challenger with a 4speed. the w-2's are a way better performing than the eddy's. even when i built my motor muscle motors told me i'd have to spend another 1500 on the eddy's just to get them to flow enough. keep in mind this is canadian dollars, so for the heads it was 2000.00 and for porting it was 1500.00 = 3500.00. this is just my opinion. there are alot of good performing heads out there but if your going to have to spend 3500.00 on a set of eddy's why not just buy a set of indy's and be done with it, those heads are basically taloired for a stroker smallblock as are a set of prepped w-2's.
