There is quite a bit we can do to get you more power from your Stag engine but bear in mind that there is a reliability trade-off as the Stag engine is not that robust. If you want better reliability a Rover 3500 conversion with a Rover 5-speed gearbox and a Holley carb on an Offenhauser manifold will give you 155 bhp. Or if you want even more power you can go the whole hog (and why not?) and fit a Rover 3.9, 4.2 or 4.6 fuel injected engine producing over 300 bhp. I can help you with everything you need and shedfulls of advice.

HIGH PERFORMANCE OPTRONIC IGNITION KIT Suited to sports performance engines such as the Stag, this kit gives you all the benefits of the Optronic system but in addition comes with Lumenition's own "Constant Energy High Performance" low-resistance, high quality sports coil, electronically matched to the Power Module. This coil has only 0.9 Ohms resistance compared to 2.5 Ohms on your standard coil. The microcircuit control of the coil current gives optimum performance over speed and voltage range ensuring constant maximum spark energy at the coil. Variable dwell angle, optimising energy use to prevent low-speed coil overheat. Automatic switch-off, preventing electrical damage in the event of the ignition being left on.
