Ive heard bad things about the Howell, never heard of the Edelbrock, probably good too..
The Weber setup gives you everything, but I think you do need to get cliffords alum. intake 250 -300.
I spoke to a guy about a year ago when i was pricing exhaust manifold and Weber carbs. he told me about it then, they were testing it out in the CA desert. (it was not advertised then) said it was programmable on the fly with a laptop running windows!
Redline distributes it and I think you get programs to "load" for driving styles desired. He said they had torque programs, high end power programs, and basic economy etc.
worth checking out, although it is more expensive.
You cannot do that with howell but youll save money.
