What kind of power should this combo be making??

Kinda new to this stuff guys so if I miss something or use the wrong term/context, feel free to correct.


400SB, 4 bolt main, bored .020, decked .010 & align honed
Stock crank & rods
Keith Black flat top pistons
Comp Cams Magnum Camshaft Part # 12-211-2
Duration @ .050 224/224, lift .470/.470
Stock heads w/ competition valve job
Stock stamped rockers.
Mallory Unilite dist w/ Hyfire VI-A ignition

Also anyone have recommendations on where to go next? This is a street vehicle/weekend cruiser. I want strength & reliability over anything else.

Roller rockers?
Better heads?
Been told I need to feed it more fuel... will a 750DP do the job?


What do ya think??

Thanks for any input.
