I think there is someone that makes adapters for the 394 to accept most Olds/GM trannys all you have to do is specify which one. I just can't remember who it was. Give me some time to look over all the junk I collect from car shows and such. About the engine, you should be able to compensate a little by backing off on the advance a little but she will still knock under hard acceleration because they do in fact need high octane fuel. I think the 394 was a 10.25:1 cr. Some people have used additives but that would get expensive for a daily driver.
