Re: 5.3 with sm465 4 speed?
I did this swap on my C10. 5.3L with a SM465. I am not privy to the programming changes needed as I just sent the PCM off to be programmed by the LT1swap.com guy. But I assume it involved deleting all the auto trans related stuff, and likely a manual trans spark table pasted in. It's not as smooth as it could be when getting on and off the gas be that's because I don't have a VSS hooked up. Once I get the TKO in I should have the VSS working and we'll see then.
Yes there is a spot for the pilot bearing in the 5.3L crank.
As far as hardware I used:
Flywheel - Sachs NFW1050
Clutch kit - Exedy 04081
Flywheel to crank bolts - ARP 330-2802
Pressure plate bolts - ARP 134-2201
Pilot bearing - GM 12557583
I used the ARP hardware since it was about the same price or a little more than the OEM GM hardware. The Exedy kit comes with throwout bearing and holds the power just fine, feels like a stock clutch. Towed 7k lbs no issue. The SM465 was factory installed in my truck, with the 1" setback plates (Car shop CSP2370) no driveline mods were needed. Any other questions just ask.
