That's just given me an 'AHAH!' moment... about 30 or more years ago I had our Chev 216 rebuilt by a company in Brunswick I think it was... anyway it was when I was working for Hughes Auto Spares which is where things like the NOS distributor came from. It always had a light knocking in it, even though everything else seemed to be good... the crankshaft and big ends were done so it seems the noise may just be due to the gudgeon pin bushes. We fitted the cast iron pistons as I was able to get them NOS at the time.
