Welcome, From Phoenix, Arizona!!

I have that SAME vibration, but noticeable when driving over 2000 RPM. I have changed/updated everything that's been mentioned. Still- Thrummmm- Thrummmmm- Thrummmmm- Thruuuuummm. The only thing that I haven't done it to replace the rear tranny seal. I also have a leak there.

Just sayin'. If you currently have your radio/unit connected to two "really good" rear speakers, you need to have either a second stereo output on your unit, or simply splice into each of those speaker lines running to the rear to get sounds up front. But what I'm getting at is; I've faced this...

This might be a good time to repost the fact that I found a second build sheet under my carpet and sound pads, for a '73 Mach-1 in med metallic blue, 3 speed manual trans, and med blue vinyl interior. If you're in need, this could be yours.

Just a thought from a friend of mine. Any of these simple "kill-switch" ideas can be improved upon, by not using a switch at all, but installing a spade fuse socket instead. Park the car, take the fuse. It won't start, unless they happen to have a fuse on them.

Welcome. That's a grand introduction, anyway. Best of luck to you on your build!

Welcome to the forum. It would seem to me that you're going about it correctly. If you're in Texas, the rear louvers will be a great asset! I'm in Arizona, and my louvers, although aftermarket jobs, keep a lot of sun and heat from wrecking my interior.

Stared at my engine bay, until I got a call from The Damper Doctor. He said my Harmonic Balancer is going to come home starting Monday!!

This is a seperate pulley bracket. The compressor mount is a seperate unit on this car which I will be offering later.

I have an A/C idler pulley and bracket that I removed from a 351 Cleveland. The pulley bearings are smooth, and overall the bracket is in great shape. I have included three pictures showing all sides of it. I'm asking $120.00 for it. I have other A/C stuff I'll post at a later date. Please P.M...

Welcome from Arizona!

For every DIY-er who has an infuriatingly difficult-to-find problem in acceleration, I have found what the problem COULD be. I’ve had everything from my engine just flat-out die when I feathered the gas pedal to running fine with a little stagger that I just COULD NOT get rid of. Timing was...

Welcome to the forum, from Arizona. You have a beautiful car there. Congratulations for the stick-to-it-tivness and hard work!

Great idea Hemikiller. To my ear (through the video, anyway) it sounds like a valve train problem, or a tappet. I'd say try the brake-on throttle test, and see if it's something simple like an exhaust leak at a cylinder.
