Im getting ready to start building my 327 and i am starting to aquire parts. I got a high rise single plane intake on the way to go along with my vortec heads and billet/forged 327. It has a comp ratio of 10.5:1 and i plan on running a 250 shot of nitrous and a big cam (with headwork of course) I have been seeing these demon carbs on ebay and wanted to know if you guys have a specific carb that would fit my needs, since this guy has many avaible. He also will hold them for 30 days with a $100 deposit.. Im looking for high end hp. See im new to carbs and dont know if i want a vac/mech secondary. electric/manual choke ect. You can buy the 650's and he can get you a 750 if you want. they are remanufactured and only cost around $400. This is going to be a weekend driver/ drag car with a huge cam, high stall ect. What do you guys recommend.

here is a link to one of the carbs

650 double pumper.

 

I'll say 750 because you're gonna be spraying so much. $400 for a remanufactored Demon? Why not buy a brand new one for $39 more?

 

good point im trying to figure out what cam i am going to get first, i think that will help me decide

 

What kinda cam are you lookin' to run? hydraulic? solid? solid roller? hydraulic roller?

 

Why would spraying require a bigger carb? The spray is adding its own oxygen.
