Sure, right. Invalid opinion. So what changed in the last 10 years? I still will not touch one. Keep tuning, rebuilding, and driving your Holley on the street. My friends have learned, and they both race. Neither has a Holley on their street cars anymore. As a matter of fact, one called me up to say how great the AVS 2 worked on his street rod after he got tired of dorking with the Holley. The other pulled all his stupid Holleys when his brothers beautiful 55 Chevy almost burned to the ground. Keep believing the "race" marketing and buying all your tuning parts.
