Just been to power to get my car checked after i rebuilt the bottom end.

Ian there reckons my big ends have gone

Ive just put new pistons, bearings, crank has been polished, new pumps and its still knocking.

oil galleries were cleaned. block was put in parts cleaner.
Is there anyway it can be the cam or is it definately the bottom end, because im coming to the end of my tether.
