I have no pics of the mods currently. I *do* have one modified DGAS carburetor in pieces, it has the venturis bored out to 30.1 mm (from 27mm stock), the auxiliary venturis streamlined and thinned out, the throttle plate screws and throttle shaft trimmed down, the choke tower radiused and polished, etc. I have another one I did on a friend's car with 2.0 block/1.5 head, and in fact that engine will be coming out soon to be replaced with a 2.2 litre, so that carb may be available for inspection soon. I had another one of these modded 38 DGAS's on my old Ascona, it really ran well. Needs higher compression to use it on the street, the larger venturis would hurt vacuum too much on a low compression street engine....mine had 11.02:1 compression...it pulled nicely from 2500-7000 rpms. I forget the actual flow numbers, but I seem to recall all the mods improving flow by *about* 60 cfm over the DGAS's stock 330 cfm.Travis said:So Bob, you must have known that one of us would ask about your airhorn mods. Care to elaborate? pics?
