Help Required: Slant 6 Engine Identification
In Australia, we recognise the 3-welch plug engines as 145hp and 5-welch plug engines as 160hp.
No, sir. The 160hp version became available in the 1967 VE models, but the 145hp version remained available alongside it until the Slant-6 was replaced by the Hemi-6 for the 1970 VG models. The block is not different between the 145 and 160 versions -- just the manifolds, carburettor, air cleaner, linkage, and some other bolt-on bits. The difference between 3- and 5-plug blocks is when and where they were cast. US production of 5-plug blocks began in late 1967 for use in 1968 models. According to the R-VG factory parts cattledog, 5-plug blocks were originally installed in Australia starting with the 1969 VF models.
All our engines have the oil filter remotely fitted to the manifold side, with pipes connecting to the oil pump.
Well…not counting the R (oil filter on RH inner guard/fender) and S (oil filter atop water pump) models.
The engine in this car has 5-welch plugs, the oil filter is fitted directly to the oil pump behind the distributor.
That's the standard LH-drive oil pump and filter configuration.
Can someone identify what this engine is originally out of? Engine number is: PF225R-24540814
PF: Probably actually PT, engine built at Trenton Engine Plant (other option is PM, Mound Road plant)
225: Displacement
R: Regular-fuel engine
2454: Engine assembled on 16 April 1968
0814: Engine serial number for that day's production at that plant
If your car has an automatic transmission, you have to hope whoever swapped in this engine knew that when putting a '68-up engine in front of a '67-down transmission, you need a ring to take up the space between the small-nose torque converter and the large-bore crankshaft, else transmission front pump bushing and seal life will be short.
