Old Edelbrock Tarantula Intake Any Good?

The Tarantula will do, but you could do better I think. I think, IMO, a RPM would be the way to go.

Go for the 3bbl Holley. Carter also made a version for the pontiac racing effort. You'll find the 3bbl. works very well in the high RPM range. If you ever decide to give it up, let me know.
