About 12-15 years ago, I kept seeing this nice looking '70 Monte Carlo with a FS sign in the windshield. I drove past it for 2-3 weeks and commented to the wife every time. She eventually said "why don't you call and test drive it." So I did. I got out, it looked decent in the dark, shiny bright orange paint, black vinyl top, decent interior. It started right up and had a very lumpy cam that sounded great at an idle. I think they said it was a small block 400, but it may have been a 350. I don't remember. When I think "super lumpy cam" I think "this is something that doesn't see much power until the RPMS get up there (3000-4000 rpm). I asked the guy if he knew what sort of gears were in the car. I'm pretty sure he said "2.56". Yeah, it sounded good, but was REALLY slow compared to how I remember my first car. I don't think we EVER hit the power band. It sounded fast going slow. It may have had other build issues as well. The person that built it certainly had no idea to make all of the parts work together.
