I'd throw the edel 600 on the truck for MPG's and low end TQ,sell the edel 750 and the holley dp, buy a reman speed demon 650 preferably with annular boosters, Theres an article out there where they compared a reg demon and a demon annular carb on a 350 or 383 chev the annular carb produced like 100 ft lbs of tq more below 2500 rpm and about 25hp an beat the downleg booster carb all the way around in power and BSFC.I think it was on the super chevy website.
Autolite 4100's they say are some of the best carbs made, why? annular boosters, BTW summit has re-introuced the summit version of the holley 4010, which is much like the autolite but the holley version for a pretty decent price but I still love demon carbs.
I bought a custom made prosystems 950 hp for my 408 built to my exact combo,it cost me 600.00, I bought a reman 750 annular mighty demon for about 400.00 off ebay and my car runs way better (idle,part throttle, warm up and WOT) and it is out of the box untouched.
