yes, my 40ish old series 2a with its 2.8 6cyl nissan diesel, 3.5 defender diffs, fairey overdrive and free wheeling hubs has really surprised a lot of people when i cruise up behind them on the freeway at 115kms ph and theres still power left, i normally sit at 100 and the lany is steady as a rock. if u want a good conversion there u go.
