Yeah there are some great results, the ls series really are quite detuned. I had a cam(224/228),spring,otr setup in my old vx clubby and it pulled good numbers.
I've been lucky enough to see a defender with ls1 fitted over here at WA Performance and it looks great.
Good luck with your conversion. Will be interesting to see how the driveline goes and what gearbox you go with !
Cheers,
Peter
