Recently aquired 66 Malibu. Previous owner couldn’t tell me a lot about the setup. It’s badged a 396 but it has a 350 in it. Seems to be a pretty hot motor with a solid drivetrain. Has Holley intake and alum heads. Also, came with a recently installed 770 street avenger but evidently had a 750 demon on it which came with the car. It has a TH350 with a 9” Ford Rearend with 3.70 gears. Needs to be tuned. Boggs down when you try to launch from a dead stop. Electrical needs some attention because the tail/brake lights don’t work when the headlights are on. All the windows need to be adjusted and the interior door handle needs to be replaced. She is very pretty and does turn heads. My little men sure like it and I look forward to wrenching on it with them in the future.
