What is your goal? More power? Better looks? Better drivability?

Some people just gotta have the true weber carbs. And that's OK, if that's what you really want. But tuning them can be a real bear unless you really know what you're doing.

But, there are a number of EFI solutions out there that look as good; or maybe better, depending on who's looking. Easier to tune, self adjusts for things like water temp, air temp, altitude, etc. Cost is about the same - depending on options of course.

If mileage is a concern, EFI usually gets better mileag over carbs, due to more precise tuning. Although not many of us are are trying to build a 25-30 mpg car, good mileage is always a bonus. Especially with a big block and a small fuel tank.

My 427 gets about 20mpg in steady highway driving. Yesterday I went to Denver for Cruise Colfax. Up the highway to far west Denver, on East on Colfax all the way to I-225, back on Colfax to I-25, and then south to home. I got 15mpg; didn't even use a full tank of fuel. And the engine makes well over 500hp.

And, best of all, they usually make a little more power.
