Rover V8 EFI ECU or carbs dizzy?

[Talonmotorsport]

I've gone and brought myself a 3.9 EFI for a wopping £27 it turns over by hand but will be taking both heads off and have a peak inside. I've brought a set of SU carbs and manifold for £20 and spent another budget busting £28 on a full set of gaskets for both the lump and carbs. My best find though is a LPG front kit that suits both carbs and injection for £74 so just a tank to find. As for the gear box the TRANSIT mt75 bell housing clears the v8 fly wheel so just a small amount triming to do so that the starter clears and fab up an adapter plate. Failing that can you run a gearbox at 5-7' on the wonk?
