hi :( i have a '77 procharged (P600B) vette 4 speeds manual in Spain and often have these problems: 1) the car will toss and refuse to start moving if i do not rev at more then 3.000 rpm and will do the same if i floor the throttle in any gear under 2.500 rpm 2) after a 20 kms run at high speed i'll start noticing a strong smell of burnt oil, if i reduce speed that will disappear. anybody can help (hope yes...)bye Giuseppe
