Engine cutting out at 5000 rpm

Any quick ideas on why my dad's car is cutting out around 5K? He has anluminum genesis crate engine (468 or 482), demon carb, holley elec pump (only a single fuel filter upstream of pump) MSD6AL box. Only has 1000 miles, but I believe has always done this. Car run great until then, then its cutting out or starving it seems (I probably couldn't tell the difference) He's replacing the filter tomorrow. I wired in the MSD. Can you mess that up to where it cuts out only at high rpm? I think he has really good wires with looms to seperate all of them along the head. I haven't changed the chip to see if that affects anything (has 6K chip now). Hell, maybe he has a crimp in the fuel line? I know he messed with the quite a bit replacing fuel pumps.
Anything else easy to check?
