This Slant retains the standard internal characteristics of the 225, both bore and stroke. The biggest difference is the intake and exhaust manifolds, the carburetor, and most importantly, the cam. The RT cam is exclusive to this model and to Argentina (from what I understand, the RT cam has a 273° duration, but I'm not sure). The carburetor is a Holley 2300 with a 40 mm bore diameter.
This engine produced 174 hp at 4,500 rpm and 333 Nm or 246 lb-ft at 2,400 rpm. Coupled with a 4-speed gearbox and a 3.07 final drive differential, the Polara RT reached top speeds of over 180 km/h (112 mph) and could travel at speeds of 130/140 km/h (80/87 mph) at just 3,500 rpm.
As for my particular engine, the manifolds had been replaced due to fuel economy, but the engine itself is quite healthy and still had enough power to burn wheel easily. We were recently lucky enough to find another original RT engine with all the missing parts: I'm sharing photos of both Slants.

Thank you very much. Regarding the Slant details: As I mentioned at the beginning, the Polara RT comes equipped with the high-performance 225 Slant Six, commonly known as the Slant RT.
