My V8 3.5 recently crossed 100k miles, she's running well on LPG mostly through two SU carbs, a very old set up. She also is fitted with a nice exhaust system and headers, I'm getting around 320 miles to a 90 litre fill up too. This improvement of about 60miles is down to running advanced timing and having replaced all the leads, plugs, coil etc (can't emphasise enough how important the ignition is on LPG)
I keep reading on here that at 100k the cam in a RV8 should be changed, the timing chain will be slack etc. Now, i have good compression in all 8 cylinders and under the rocker covers is as clean as a whistle, looks like new under there. Should i be changing the cam? And if so, what type? i would like a bit more torque, but maybe a standard overhaul will give me enough? Or i've also read that a 3.9 cam gives a bit extra?
What do you lot recommend? I mainly drive the car on the road but do do a bit of tame laning too.
