I did the same on my 442 and its better safer at least for something that does see the street some and cheaper and easier than a sump & cell. I am just not a fan of the gravity fed out of tanks electrics when there is a better route available for the gbodys. But if its for a drag car as stated and the whine or rear ended danger does not matter or you already have some parts and or you need something for north of 600HP an out of tank can make good sense. I apologies I am drawing a blank at the moment but there is also a Pontiac guy with black car that has an excellent well thought out drag car setup with great pics etc also. He may chime in.
In the muscle car era if it had a small block it was your moms car.
