For a 1987 Cutlass Supreme 350 Rocket, i need a diagram of the vacuum lines on engine for the heat. something has to be wrong because i now have no heat. any ideas?

So it blows cold air? Is the coolant reservoir full? Here's a typical heater diagram.

dude the 87 didnt come with a 350 rocket.....let me guess u go make it a monster truck too...if yall boys go be dealing with cutlass please stick to the real factory specs and stop cutting up and taring up these good classic cars...u messing up the value as a whole.if u dont understand how the classic car game is stay out of it please

hers a idea...take it out and put the 307 or the v6 back in it

why the fuck you give a damn what he spends his money on? tell the same shit to the people who makes standard trucks to monster trucks. he asked for help, if you aint gonna help then shut the fuck up

The true olds rocket cars ended in 1972-73.

TBH all OLDS V8 engines are Rockets!...
