Hello Al,
So you are new owner of a Classic thats Chevy powered. I hope you enjoy many miles of fun but mainly the Cobra people are what it is all about, a great group with a common love.
The Edelbrock system does have a few good points but for my dollar just not a system that allows owner control and system design like many others for making it fit your engine. Edelbrock requires you to fill out an engine spec card and burns a chip with fixed points to their set point. It does allow a small window of + or - from set point but if you want more change than the window you have to wait while they re-burn your chip and mail it back to you. Most other companies allow you to change from fire breathing dragon to grannys car for church with the stroke of your laptop.
For me Holley Injection is the better choice in terms of function and performance. I do admit you are on your own for the old system 2 seconds after they release a newer revision or model. I bought a system on Monday and they released its replacement on a Friday so no longer wanted to talk about the old version other than send it in for warranty repair if broken.
I am also a fan of throttle body over port injection for the do it yourself application. A global change or problem is something I can find or understand. The higher tech. of port design is too much for this mind to deal with. I had hard time learning electronic over the old mechanical injection and am just now getting comfortable again.
