I have a feeling i am being hoodwinked. I took a 67'Camaro with a 327 to a garage to have a edelbrock performer and holley carb put on. I was given an estimate of about 450 to 500 bucks. Now they're jacking it up to a little over $600 and making me buy theyre valve covers, saying that for some reason mine wont fit the edelbrock intake? is that by any means true? i need info asap. please help, and the more people that write and agree the better because i plan on takin this to them if im told that they will work
