Yep, it's good, but the LD340 and LD4B will run great from idle to 6000 and I think that they make more in the low and mid range than the Air Gap. The air gap may be a little better on the top end, but how often is a street cruiser going to see that RPM???
I would stay with the older Edelbrocks if I had a choice. I have a few stashed away for future needs...
