I also have a 1980 rallye in orange. just bought it last week at a dealer auction dirt cheap. 77,000 original miles. someone put an offenhauser 4bbl intake and holly 390 cfm 4 barrel. the only problem with the car is it's missing the rear spoiler on the deck..
Next month I'm pulling the motor and installing one of my circle track 2500 stroker motors. 13:1 compression Isky cam, wiseco pistons 5.7" crower rods... should wake the car up for some fun street racing. I'm also swapping in an 8" with 3.80 gears
