Doesn't have to be super expensive.
Truck oil pan works great, just plan for its depth in the build- no need for accumulator afterwards- unless you just want the insurance of it.
Stock manifolds flow great and don't put off near the heat of headers- bonus; they typically clear your driveshaft and already clear your motor mounts....
Build around truck accessory mounts, they're higher than the f-body beltline anyway.... another plus the harness already fits it...
Biggest cost is harness and tune, dbw or custom cable, torque converter spacer, intake ducting, and I run my temp gauge tapped behind the thermostat on the engine side of the water pump and you can tap the oil cross over cover above the oil filter for your oil pressure gauge.... no adapters needed.
But it can be quite expensive if you want it to.
