LS 5.3/NV4500/NP205 swap

[DBear]

Good evening, looking for some info. I'm swapping a 5.3/nv4500/np205 into my 71 k10 suburban, that is originally a 350/sm465/205 truck. The nv4500 is a 93-95 model. I have already purchased the Advance Adapters bellhousing kit. I do not plan on running a hydraulic clutch. What I need help with is the flywheel, pressure plate, clutch, etc. I was originally going with the stock 350, so I was gonna use the clutch and all from the sm465, but changed to an 02 ls 5.3. I know AA has a kit for flywheel, clutch, and pressure plate, but very expensive. Could I piece mill different factory parts to save money? If so, can someone lead me the right direction? Thanks in advance
