Update: 71 Demon SRT6

I sent the carb to Custom Rebuilt Carburetors in Middlesex, NJ. The carb is back in my possesion now. To be honest, I'm not sure if its gonna work how I want it to. On the invoice it says they put nitropyl floats and a light secondary spring. But from my understanding, on a blow through carb, the throttle shafts need to be pressure sealed. So I called them to talk to one of their techs about this and he said that demon carbs already have a very tight seal and it probably wasn't necessary. So I reassured him I wasnt an expert and trying to question his professional opinion, BUT from EVERYTHING I've read, some sort of precautions must be made to that effect. Then I referenced the differences on a Demon "blow through" carb and mine, and such. He told me that Barry Grant might just be "blowing smoke" with those selling points, trying to sell $600 carbs and that he thought it would be just fine, BUT he'd do a little research, and talk to guy he knew that deals with Demons more than him to see if more work must be done, and call me tomorrow. I believe they only charged me $245 which I thought was pretty cheap, but he told me my carb was in very good shape(which makes sense since I only ran it on my vette for about a year). And more pics are coming 6pakattack!! Should have some more up by the end of the week!


ok im no carb expert, but trust me the shop that did my carbs,,,they are the real deal,,,and not cheap,,if you want i could get you there number,,,call them talk with them,,ask questions,,dont tell them right off you had work done,,compare what they tell you,,
my stock carbs were ok after the blower (roots style) built heat,and they had a mind of there own,,,when it was cold or hot,,,orignally flowed 650 cfm,,,
now after modifing the throttle blades,,massaging the venturies,,,changing the squirters,,,they flow 862 cfm each,,,they made it a 4 corner idle circuit,,,demons come that way,,older hollys do not,,,

they drilled out the passages in the metering system,,,and put in jets,,,granted it flows a ton of fuel,,,but if you want HP you need fuel,,,

this car starts and idels right now,,every time,,,set ya right in the seat,,,a cold hard GRAND to do both,,,,
