4.8L / 96MM Piston problems Rover V8

[debaron]

About to start an engine build for the Chim using 2618 alloy 4.8L forged pistons. Been looking around and there are two threads about 4.8L builds that have both gone bad using the same pistons I have. Seems it might be down to the bore clearance being too large coupled with short side skirts.

Any advice on what way best to go? Engine not linered yet so not too late to go back to 94mm cast Rover ones but means I'll prob not get to put the supercharger on....

anyone running a 4.8L that hasn't had problems??
