On my 408 stroker for my truck, I undersized it a bit...running an eddy rpm air-gap w/ a holley street avenger 780cfm on it. Works great. Stock gears and stockish TC.

If going with a DP, if you've got a manual trans, it's all good...nothing better. If you've got an auto, make sure you've got a higher stall T/C...
