It ran, but not very well. It would idle ok but I could barely keep it running when in gear. I just drove it up and down the driveway. I did a compression check and found cylinder 8 was 30 lbs. The rest were around 120. The inspection sticker in the window was from 1985, so it sat for a long time. The 440 has the stock intake but came with headers. I had to put on an Edelbrock 750 to get it to idle.
