It's the same reason most morons are into chevs, they just don't know any better! And apart form all this what about all the other problems holleys have, the stripped out threads, the baseplates that are made out of cheese, the fact that the basic design with all the leaks and all the other problems is out of the 50's, the fact that in warm weather they wont start when hot because they boiled over when you turned the engine off, this is a classic, holley couldn't fix it so they gave it a name... "flash boil" the fact that a tiny spec of dirt gets in them and they go haywire. I could go on and on if you guys are happy with junk so be it!
