Edelbrock 7577 question

i have an intake i bought from kmj on ebay. i was looking at them again last nite as i might need another 1 and they are only 199.00. but there is no bypass hole under the t-stat hole. i emailed them and asked if that was a mistake or if that is why the price is so cheap. not heard back yet. i bought my other one last year but just put it on shelf. will need to inspect it. here we go.
