[QUOTE="tonybolton, post: 467562, member: 3432"] My brain is telling me I should ditch the carb route and pursue a modern EFI system that I see offered by MSD / HOLLEY / FAST....etc etc..etc. However, when looking at total cost involved my wallet is saying, "Hey, maybe just a better carb setup would work!" The motor in question is a 440 Chrysler bored to 505. The current setup is two Edelbrock 500's. In my opinion....it runs horrible for what it is, however this is the way my Dad wanted it so thats what he did. It does LOOK good, but i'm not that concerned as I prefer performance over looks. The carbs were semi-worked many years ago and from what I remember they just couldn't get the progressive feature of the duals to work so they were just linked together. In my driving experiences, this causes the car to fall on its face if you mash the gas from an idle or low-ish RPM. Then after it falls on its face it throws you back in the seat till redline. Part throttle tip in is no picnic either. It's very finicky. My plans are to run a few road courses, dragstrip passes and local autocrosses just for shits and giggles but mainly just get in, crank it, and drive it. So, what i'm asking is....can GREAT driveability be achieved by going to a more conventional single carb setup? I know it won't crank up/be as efficient as EFI, but if I can get pretty close to EFI driveability I think i'll be happy. I'm also concerned with fuel bowl slosh when encounter quick or sustained corners under throttle. I imagine this issue has been tackled before, but i'm completely ignorant on all things carb, and for that matter, aftermarket EFI. I'm not against paying for someone elses labor/knowledge on this. I'm a nut/bolt guy and I can handle that part. I'll eventually put a complete suspension under the car but would like to resolve the motor issues first and go from there. Thanks for any help or advice pointing me in the right direction. [/QUOTE]
