Okay, you're running high flowing heads, high flowing intake, high flowing exhaust, 505 cubes. Why restrict everything with that 850 carb? I'd be looking for a 1050 Holley for that beast or that 3916 three barrel as stated above.
Really? You're suggesting the guy put a Dominator carb on a street car? That seems like a bad idea, the guy clearly isn't building a race car and he doesn't have a 4500 intake.
He doesn't need an intake for a 4500, here's a pic of a 1050 that's not a 4500 and will bolt right on his intake.
I love the smell of Deer guts in the morning, it smells like... VICTORY!
