Even with one cylinder down you should be able to go faster than that. Have you checked your timing or timing belt?

well the car is not mine yet but they are asking 400 body is in very good con. other than a few surface rust spots. the interior is also very good. he said its just the motor has problems he said he took it to a shop and one cyl. has low compression they said the know the symtoms of a bhg and that was not the prob they said the engine was toast so... not sure cuz i cant look at it but what you guys think?
