Aren't all series 1 VT Senators 5L ?
And I assumed by the multiple mentions of 220kw the OP was referring to ATW.
Nobody relies on Flywheel power figures these days except manufacturers really
Well you should know by now that HSV put the engine kw power on the back of all their cars wich also depicts the model.. 185 is the first 5L, 215 is the first 5.7 stroker, 195 is the VT 5l, 220 is the VT 5.7 stroker and so forth through the rest of them.
