I bought this car in 1989 when I was 17. Wasn't this cool at the time though. I need to sell it. It's 10.25:1 compression, 462 cubic inches, aluminum Stage 1 heads, 7/8" primary headers, 2.5 full dual exhuast, 12 bolt 3.31:1, roller rockers, split duration high lift cam, blah blah blah about 400 hp and well over 500 lb ft at around 2700 rpm...8mpg through an 8oo cfm carb, and it really could use a 1,000 cfm Thermoquad; this big Buick mill needs more air. I didn't paint it or stitch the upholstery or build the trans or rear end and I didn't do the machine work on the block and crank or balance the rotating mass. I did everything else. Unfortunately old cars need TLC fast and I drove it too much, needs TLC again
