Forged Piston to Bore Clearance - Rover V8

[debaron]

Round to getting the Rover V8 finish honed for forged Icon pistons - 2618 Alloy

https://www.uempistons.com/index.php?main_page=ind...

- Manufacturer calls for 3.5 thou piston to bore clearance boosted - 4.5 thou NA

- Local Skyline engine builder agrees around 3.5 thou although may rattle a bit when cold

- TVR Power recommend 2 thou max

Anyone with experience of 2618 Alloy in Rover V8 know an ideal clearance or concur with one of the above?

Thanks
