Morning guys. I have stripped my HC viva ready for some welding and eventually mocking up the engine transplant. I was always going to run a 16v XE with a Type 9 gearbox through a 4HA axle, and I have all the parts ready to go. But at the last minute I've decided I may want to go whole hog and run a small block V8 instead.

What would my best option be and what gearbox would be best to use? I would prefer a manual but i'm not overly fussy. I don't mind having to mod the tunnel but I don;t want to be cutting too much away so that nothing original fits back in place
