I have the opportunity to purchase an Edelbrock LD4B intake manifold alone or a stock cast iron intake (?year) with an Edelbrock Performer 600 cfm carburetor for the same price. I want to put either one of these on my '71 Dart GT with a 318, auto (A904), 3.23:1 sure-grip 8 3/4" rear end. The car has electronic ignition, and dual exhaust (manifolds, 2 1/4" pipes, and FlowMaster 40s). Everything I hear about the LD4B is that it is great for a 318 (port sizes match). But, will there be a significant performance difference (excluding the weight factor) between the LD4B and a stock cast iron manifold? Basically, if I go with the cast iron manifolf I get the Edelbrock Performer 600 carburetor free. Is the LD4B worth giving up the free carburetor? Opinions please!!

LD4B, excellent intake for 273/318. Taller than the Performer and has larger runner volume. LD-340 was its big brother and those go like hotcakes. Very good design, wide operational range, surpassed by Performer-RPM. May be similar to Stealth in performance, but probably cheaper because it is older. Used on early 340 drag cars before Ld340 came out. Either way...it your choice...and with the economy the way it is..if you cant afford a new carb I would go the stock way...especially if you are a daily driver and the carb being good...ie rebuildable...my 2

Vizard ported a stock intake with a die grinder, just rounded off the corners, and narrowed a few walls. He claimed that his home ported Chevy intake was superior to ALL aftermarket intakes for a stock 350 motor. Of course, 30 lbs off the front end is nothing to laugh at either with an AL intake. If yoiu need a carb, get the stocker. Youll probably not feel any difference.

Don't forget the 4bbl kickdown linkage when you do the swap. Either that or modify your 2bbl one to work or get an aftrermarket cable kit.
