Cliff is “the” guy for quadrajets, he literally wrote the book on high performance modifications. but he can get pretty far behind if you want him to build a custom one. Last year about this time he told me he had a 6 month wait, everyone sends him stuff as spring gets near. I didn’t have that kind of time so I tried quadrajetpower out of Texas, after a couple of long conversations with them. they built a 800 cfm that’s on a 467 Pontiac in my wife’s 69’ firebird. I wouldn’t hesitate to go with them again, they did a nice job.
