As I am getting everything ready for my timing chain install, I realized last night that there are two sections in the shop manual for the 5.0 V8 Petrol Timing Chain replacement. One for INA and the other for TSubaki. After doing a little searching I found this:

There were two types of timing chain systems fitted to the 5.0 v8 engine - Tsubaki, with 6.35mm chain pitch, and INA, with 8.0mm chain pitch. It's important to note that with the different chain pitches, the only thing common between the two are the guides and the tensioners. Everything else - the chains, the VVT units, the sprocket on the end of the crank, the oil pump sprocket, and the auxiliary driveshaft sprocket (which can't be changed) are all the same drive pitch.

How can we tell what Timing Chain we have? Vin number?
