The one you show Cliff is one I bought for my current 77 280 a few years ago. When I thought I was going to pull my head which I still have not done. I mean intake

I agree Dave.

Good deal. Mine is still quiet after re-installing my OE knob.

I had a similar issue a few months ago. Was convinced to remove my shifter knob and I'm glad I did. It was the culprit. Hope its that easy for you now that you have done all that chasing.

I've used the one from MSA 3 times on 3 different Z's and have had good luck with them. Maybe I got lucky?

Chiefmd, I can't believe how much these things have gone up in price! Personally if what rockauto has is correct, Bosch, I would get it. JMO.

Haha! Me too!

Thats the 75-77 one.

Right. When you mentioned your "receipt" I figured it was in reference to your 77, not his 78. Sure would like to do the fuel rail update but can't. I would fail the "visual" part of the emission inspection here.

The 75-77 is a different one from the 78-83 one.

Wow, that's a serious price increase now!

Its the same one Cliff, 78-83

Rockauto has them for $96. (Bosch) according to them. MSA $125. Zcardepot $159.00 Not sure why the wide range in prices.

I ran SU's on my 77 for a few years, when I was in Las Vegas, and didn't have any problems with the stock linkage or its location. The plan was to do what you did Philip but never got around to it. But then had to remove them when I came back to CA.

I got mine back, only because I kept asking for it back.

A cartoon from back in the day. Watch an episode and you'll see what I mean. You're not that young that you don't know who the Flintstones are, are you?

Ya-ba-da-ba-dooooo.... You could just Flintstone it. That's ugly!

Great find! So glad you are considering taking it to original. And she looks nice and straight which is a plus. It also has the typical rust places so there is a lot of good repair info here. Good luck and keep us updated.

I would just love to drive it.

This is what I have thought about a couple of times. I've never seen a stock L engine run at 20inHg. Not that it isn't possible? IDK. I just haven't seen it myself. But I have thought you should check it with a different gauge just to eliminate it.

Nobody said anything about backfire. You need to read it again.

Connect your timing light up like you normally would but instead of putting the inductive pickup on cylinder number one spark plug wire put it on the ones in question. Watch for uneven flashing. This will tell you which cylinder(s) are misfiring. But make sure the inductive pickup is on the plug wire tight.

Now there's something I forgot about. You can do the same Alex.... with a timing light if you have. Check each wire that way. It'll show you a misfire if you have one.

I probably just, between my thumb and forefinger, "wiggled" it back and forth slightly til it broke lose. I think that's how I did it, thinking about it some more.

IIRC the clock was the most difficult. Go slow! But I can't remember how I did it. Sorry I couldn't be of more help
