The 455 has plenty of torque for a street build.
The 400 would be a great strip motor, unless it is the 557 casting number.
The 400 can be stroked to 462 and can make a nasty strip motor,and will actually be stronger than the 455 , due to the smaller main journals which allow more metal to be retained at the main bosses...making it a stronger choice for a strip motor.
A cam as large as you propose for the 455 will need 9.5 compression or above, making it a not as good choice, as your block probably isnt zero decked.The heads are number ?? Have you CC ed them ?Does it have those stupid 8 valve relief pistons in it?
The 7156 edelbrock would work better with a quadrajet. Great carbs.
Also the redline is 5250 for a stock 455 bottom end. The cam you chose shows to make power higher up to start (2000) and goes to 6000.
With stock heads on the 455 and a stock bottom end, low compression...the XE 262 would be a good choice for the street.You wont need a 2000 stall converter, which will help your trans live longer, and make it more pump gas friendly a whole lot easier and cheaper than any alternative.
High volume or high pressure pumps are not a good idea.Stock pumps are quite adequate. Stock pumps are 60 PSI. Ram air 4 pumps are 80 psi,but require a "looser" tolerance on the bearings.
The only thing I would say is to get as much tire on the back as you can fit in the wheel well.You will need it for the 455.
Tires with a low treadwear number, wear out faster as the compound is softer, a higher treadwear number is harder and lasts longer. A low number is softer and gives better traction, just sayin.
