chevy 327 tilt instalment

Does anybody know at what angle does a chevy 327 have to be when installed . I freind told me that my motor is tilted to far down and thinks i will have problem with my throttle response. I have a holley 650 aqnd have recently fired up my motor and have not seen any problems yet.

when you put an angle meter on your carb mounting plate, what does it read, 3-5* is what it should be. factory intake's have the mounting plate angled at 3* to keep the carb leval.
