Smiles Posted January 26, 2012 Share Posted January 26, 2012 Good day, I am busy with some repairs on my motor. Up to now I have replaced the SU carb kits and the cylinder heads were also at the engineering works. How can I get more power from my 3.5 V8? Will it be worth while only changing the Camshaft? and what would be the best one to fit? Hennie Quote Link to comment Share on other sites More sharing options...
zardos Posted January 26, 2012 Share Posted January 26, 2012 Convert to fuel injection and Megasquirt it? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 26, 2012 Share Posted January 26, 2012 Yep, instant 20-30BHP just by dropping an EFI set on it, and that's without Megasquirt.... Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 26, 2012 Share Posted January 26, 2012 What they said. The later 3.9EFI camshaft is supposed to be a cheap upgrade too. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 26, 2012 Share Posted January 26, 2012 Yep, 3.9 cam is good, but a new set of genuine followers is a must at the same time. Quote Link to comment Share on other sites More sharing options...
Smiles Posted January 26, 2012 Author Share Posted January 26, 2012 Already spend alot on the carbs to repair, so injection is not on the books for now... I am however thinking of cutting to a 3.9... Is this possible without fitting new sleaves? Do i leave the stroke the same? Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted January 26, 2012 Share Posted January 26, 2012 Aftermarket ones are ..... no lets be honest, pretty carp Quote Link to comment Share on other sites More sharing options...
need4speed Posted January 26, 2012 Share Posted January 26, 2012 Why genuine? Because cheaper alternatives are noisy pieces of rubbish. Rhoads are noisy pieces of slightly better rubbish. Fit genuine LR. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 26, 2012 Share Posted January 26, 2012 To convert to 3.9 you'll be best off just buying a 3.9 engine... which will come with EFI anyway. Putting carbs on a 3.9 will drop you back down to 3.5EFI level. Quote Link to comment Share on other sites More sharing options...
mike080381 Posted January 28, 2012 Share Posted January 28, 2012 What they said. The later 3.9EFI camshaft is supposed to be a cheap upgrade too. So does the 3.9 EFI cam work well on a Carb 3.5, or only when it's changed to EFI? And will is it still a good upgrade if LPG is used?
