OK today I decided to do an oil and filter change to get my baseline . I cross referenced the Fram filter and decided to try a AC Delco PF48 . It fit perfect and there is plenty of room to go with the longer PF63 or Wix equivalent . So I have confirmed the oil filter is a 22mm x 1.5mm .

While I had it on the lift I studied the underside looking for any part numbers . The only part number I found was on the oil pan .... 12614822 which is an H3 oil pan . Apparently lots of hot Rodders use this pan when installing LS/Vortec engines in a variety of GM products .

Unfortunately I still don't know what model year engine I have . I will have to study the topside for any markings . To be clear the guy I bought the truck from did NOT do the conversion . He bought it from the guy that had it done .

The rear diff housing has 4.10 written on it with a paint pen so I assume a 4.10 gear ratio . Today from a standstill I got on her hard for the first time . Tires lit up and she was straight as an arrow . Locker ? I only saw one black tire line on the pavement . I will keep unwrapping this onion . I really like this truck .
