well i was trying to find out why my car was smoking... turned out to be my timing was WAY off, and caused it to smoke a little once i kicked it down some.... well in the process i got a vacuum guage on it, and it only read 12 hg at idle??? could the combination of my heads (world products windsor jr.'s) and e 303 cam cause that??? no vacuum leaks anywhere, the motor feels strong as hell, doesnt skip a beat, and was only has about 4500 miles on it.... also i dont have the vacuum canister in the passenger fenderwell right now.... could that be it too???
