Hi Jagboy:
Not sure, I have a buddy that owns a Brit car repair shop. He recently moved & had a ton of stuff he no longer wanted & certainly did not want to move it, so he let me come to his old shop & take what I wanted. He did tell me it came from a MGB. Not sure what motor?? Our car club wwwcapecodbritishcarclub.org hosts a large show every Oct. During the show we have valve cover races. So I grabbed alot of valve covers & PC'ed them for guys in the club to make racers out of them.
I'm a Triumph guy, so I could be killed

for having MG parts
Thanks
Bob
