Hey, @rvrtrash , can you do the same for mine? It's in a '73 Q code manual.

btw, thanks for sending me one, @Ronk. Finally got around to putting it on recently and it works perfectly. It's a solid feeling connection when putting the cap on now vs with the thin and degrading rubber pieces that were there before.

I have the original Goodyear Polyglas...advertisement. A little cheaper than the tires ;)

It's gonna cost $600 to fill it up in 50 years.

It's actually running pretty well again finally with the new intake on. The initial idle was really low RPM, vacuum was low (~9") and was blowing out some liquid from tailpipes. I leaned everything out a lot, lowering the float levels and turning in the idle screws from the initial 1.5 turns...

That's encouraging to hear as I just installed my new edelbrock intake with the felpro 1228 gasket and nothing else to block the crossover. Like @giantpune I just followed the instructions which said nothing about adding anything to block. If it was needed I imagine felpro would have thrown in...

Thanks, it was the choke! After loosening, it's idling ok again. Now need to re-dial everything in, but back in a good spot now to proceed.

Yeah, it's always had the ticking sound on the passenger side, probably exhaust leak. I checked and rechecked the firing order before starting, but will do again next time to make triple sure. I haven't checked balancer slippage. It's on my list, but i've been able to get it to idle and run...

Intake is on. Not entirely confident I got total sealing with the Right Stuff bead on there, but we'll see. After letting it cure for 24 hours and after torquing everything down to 22lbs, I started it up just now. Good news is it started, bad news is it's idling like crap and dying. About the...

So, old intake has been removed (that was a challenge) and new intake has been painted and ready to install. I cleaned all the surfaces, applied high-tack to the head surfaces and head-side of the fel-pro gasket, placed those on, and set the new intake on to check everything fits right and seems...

I'm still trying to get this car sorted and running reasonably well since I bought it in May. Starting a dedicated thread here, but had another here: https://7173mustangs.com/threads/hello-from-nyc-73-mach-1.43188/. It has a Demon carb sitting on top of a custom adapter plate on top of the...

Got it running again. Checked and it was getting spark at all the plugs, strength of spark seemed ok while cranking. Not really sure what had been the issue before, but once it got running, I ended up at about 22 degrees timing at idle. Setting lower would stall out, so leaving it there as it...

Not yet. Must be ignition related somehow. I didn't hear anything fire at any point.

I went to start it up just now and take for a drive and it won't start at all. It was in exact place that I left it after the tuning I did yesterday where it was running fine and restarting instantly, the only difference is it was fully cooled down now. I tried a few things like lowering the...

So, i've done a few things. I replaced the plug wires and the rotor. Between that and the new plugs/cap the ignition issue from before, where it didn't fire up while cranking, seems taken care of. It will start pretty much instantly now (when the bowls are full). More importantly, I cleaned...

Thanks @Hemikiller, the custom spacer makes sense now. I do have that 73 style intake and now that I've had a good look, I think it's gonna need to go, though that will take a little time. Aftermarket is fine with me, looks like the Edelbrock Performer is the one people use for low profile to...

So, how much could I go up on the initial timing? It definitely pulls more vacuum with more timing at idle so maybe I'll go for 20? 22? I should be able to back out the idle speed screw more doing that too. The metal spacer is definitely homemade and must be the reason for the blocked manifold...

So, I think i've made some progress. After replacing the plugs, I also replaced the distributor cap and it seems to be starting a lot better, which is pretty cool. I've got plug wires on the way and will do the unilite rotor, too, so I think that should address the issue I was having where it...

That sticker is helpful. So, i'll target 16 degrees at idle. Looks like i'll need to add a ground to chassis somewhere or get a different battery cable that has the tab. It's definitely a custom adapter plate under my carb. From what I read, the 73's had an EGR spacer which has to be removed in...

I've done some tinkering this month, though was out in Europe for two weeks for work and vacation during. I'll list out some observations and theories I have so far and planned next steps and would be great to hear feedback. For the timing, the white marker is at the 0 degree mark. Got a pic of...
