Series 3 engine in Series 2?

Hi guys, i have recently started on a project (series 2a SWB) which was a 2.25 petrol. I can get my hands on a series 3 engine, but am not quite sure whether it will fit, i know i may need different wiring loom etc. But, in basic will the engine fit on the brackets etc. in my series 2?

Thanks a lot, James

yes it will fit , it is in fact the same engine

Use the Clutch to match the gearbox.
