Unleaded question

[V8darren]

I have tried Turners and RPI engineering but they didn't really answer my questions, so hopfuly some one on here can.

Can the Stage 1 V8 run on unleaded without changing the cylinder heads?
If so does the timming need to be adjusted?
If it does do you know what the settings need to be?[

The engine is of course the Rover 3.5L V8 carb, engine No - 10G01359
if that helps.

Many thanks in advance for your help.

I've run on 6 degrees before top dead centre without problems for years.
try to get the book "know your landrover" with technical queries from the first years of landrover owner. there's plenty of info in it. most solutions have been tried and tested. if another part is being fitted they'll give the partnumbers as well.

I seem to remember reading that all the V8s fitted to Land Rovers had hardened valve seats but I can't remember where I saw it. I've been running on unleaded for 10000 miles without problems.

If so does the timming need to be adjusted?

The engine was designed for 2 Star petrol (91-93 octane) and unleaded is higher rated than that (at least in the UK it's 95 octane) so there should be no problem.

I've been running my stage 1v8 on unleaded for 12 months or so without any problems, in fact the old girl quite likes it as long as it is "super unleaded"
