Carb Tuning???

[429mustang]

Right now it has the stock open rear with probably high 2's gears (around 2.90's). As far as weight, it's pretty much empty inside, it probably weighs close to 4000lbs. I'm gonna put either 3.73 or 4.10 gears w/eaton posi and an ultimate rear cover, possibly weld on rear brace if I can fine one to fit. I'd swap the whole rear, but that'll probably be even more expensive and more complicated. How are some of the road/speed demon carbs?

It kinda sucks, I don't really want to put too much $$ into the van, it's pretty quick and definitely needs gears/posi, but it seems kind of pointless to put around anothe $1000 into it to still run 14's. Basically I just want a pro 5.0 car, it would be nice to pull a 6 et. cruising everyday to work, or just burn of a set of tires in 20 seconds. GODDAMN!
