No major problems at all.
Great car, No oil leaks, does not burn oil, crappy gas mileage but worth it to have that much power!
I was wondering if the car you were talking about was a royal or royale because I have a royale w/a 307.
I happen to own a 1983 delta 88 royal and find it to be a very sporty car and an excellent alternative to the Cutlass/Monte Carlo/Regal cars.
Its Royale to answere the first qustion all 88s built by 1984 were 88 Royales.
Thinking about getting a 1984 delta 88 with 307 any suggestions.
