It is asking a lot for a mechanical pump at the engine to pull sufficient fuel for a car that can run in the low 11s or high 10s.

I considered the sump option early on, cliff suggested that & that its better to push fuel than pull it... but being mostly a street car I chose a stock tank with a 1/2" pickup & keep the tank 3/4 full at the track. The external pumps are nice but most are loud & not very reliable for street use. If/when I go electric pump I will get a tanks inc set up or other in tank pump module, the tanks inc has a nice internal baffle in the tank. Thanks for the advice.
