carburator vs fuel injection

Daily Driver: fuel injection hands down
Weekend /Summer Driver: Carburator (only on cars old enough to not come with fuel injection)

If I had my way, my 305 would be injected. It's more expensive, but more effecient and more accurately controlled. (by controlled, I mean safer for keeping an exact A/F ratio, avoiding the boom)
a carburator is much easier to tune and you don't have as many restrictions when building your engine. it is cheaper and easier to troubleshoot and good for highend horsepower
injection is nice because of the very consistant power curve. you will get much more low end torque with injection but you will sacrifice some highend horsepower compared to a carb. you have more things to watch for when building your engine and vaccum is much more important to injected motors. you need around 11" of vaccum with injection whereas a carbed motor can sometimes pull as little a 4" to 5" under hard acceleration
just my two views

I also have an LS1 in one of my toys and it pulls good all the way up but I was just trying to give "most of the time" examples.
in reality, Edlebrock and Carter and a lot harder to tune than a Holley or Demon but most people have Holley so I went with that assumption. I think Edlebrock is a better street carb when it is perfect but Holley is just way easier.
as for the injection, yes many systems are very tunable with a loptop, but again most people don't have the laptop and knowledge to do their own tunes. a lot of them just to later model bolt-ins that rely on factory computers and when something goes wrong they either have to go to a dealership and pay top dollar or they find that no one wants to touch a car that is not a stock animal
just my useless opinions

Carb is old school - uses more fuel - not as efficient - engines don't last as long due to fuel wash in the cylinders. Carbs are less expensive initally and will not make as much power as a properly tuned fuel injection engine. The right fuel / air mixture to each cylinder is the real advantage. So I'm old school but realize the difference new school technology allows Us.

sometimes an old dog can learn new tricks but just doesn't want to take the time. I find it funny that some people swear by one method or the other when they don't even know anything about the other side of the subject. it's nice to see someone say what they like but also give an explanation that doesn't shoot the other possibilites down
