I swapped my 307 for a 350 and now the 350 is sounding bad too. It seems to be out of balance and making noise like the 307 did. I should check to see if its not just running rough or misfiring. Don't think its that simple though. IF I get another engine I should get a new one that has a warantee. I have only been running this thing since June, but its an 86 that sat for a while. I was told it was "rebuilt" but was not bored. I was driving today and it seemed fine until I got on the highway. Then it feels like a bad fuel filter or something. It sucks, but not much I can do about it. I changed the balancer on the 307, but that was a too little too late.
