We're doing the car while on vacation in Mexico, so parts are hard to come by. Hope to have it running soon :) We had it right.

Odd cylinders on the drivers side, even on the passengers, firing order is above. I had to replace my coil when troubleshooting other issues, but my spark is nice and hot white. Hope you get yours figured out, I'm still working out a few details before mine runs again! Dave, Cylinder 1 is the drivers side front cylinder.

We're trying to get it going now and are only getting a weak yellow spark. It wants to go but can't quite get there. Any suggestions?? Can you confirm the location of the number one cylinder? It has the 429. thanks, and good luck with yours. We’ve just done the heads on a 67 caddy that hasn’t run in 4 years.

They're a 20 x 8.5 with a +15mm offset. You can read more about them and the tire I put on it <a href="http://www.nslms.com/2009/08/02/67-caddy-new-kicks/" rel="nofollow">in my other post</a>. As for this motor, as far as I can tell the washer didn't do any appreciable damage. In fact, other cylinders which didn't have a washer in them have more score marks! I intend to just put it back together with a new gasket set and some cleaning, and run it! Hey Mike, nope these wheels fit perfectly! They’re a 20 x 8.5 with a +15mm offset.

I bet that washer came of the air cleaner when someone was being careless. Question for you: I'm looking at buying rims for mine. Did the rims you bought have any clearance issues? I'm nervous about ordering something that won't clear the fender skirts. Looks like it might be time for a rebuild! I bet that washer came of the air cleaner when someone was being careless.

You must have seen the smog equipment in one of the photos since I don't recall mentioning it! Yes, I am quite sure it's a 429 there are a few obvious signs. The exhaust manifold only has 3 runners, the center two cylinders on either bank share a runner. On the 472/500 it's the more traditional head setup with 4 exhaust runners per cylinder bank. There is a crossover pipe for coolant that goes between the heads, and into the top of the water pump, this was a design unique to the Caddy 429. The 472/500 firing order is 1-5-6-3-4-2-7-8 and the 429 is 1-8-7-2-6-5-4-3. I had some ignition trouble and verified that my motor uses the 429 firing order. My service manual tells me that only cars which were built to be registered and driven in California would have had the smog A.I.R pump, so there are probably more cars without it than with it. This does tell me that my car is an original Cali. car though. :-) Hey Mike,

On my 67 deVille, there isn't a smog pump, but lots of folks like to swap out the 429 for a 472/500 from the 70's because you can get parts for them. Are you sure this is a 429?
