I like that the LB air cleaner still fits...still looks factory, which is a must for me. I'm glad you kept the original intake too, I was pleasantly surprised how well they flow, considering the low performance numbers of the time. Swap out the smog era cam and you can make pretty decent power without changing out intake or exhaust.

Thank you Mr. Angus66 for this thread. I’ve been considering this or the like for my Newly acquired 77 NYB.. as Stan mentioned! What was the cost associated with your set up? If specific cost is asking too much, then ballpark will work. And please! Keep us updated as you rack up miles and data on this system. Inquiring minds want to know.. lol.. thx


I'm a Canuck (Calgary) so I ordered it through a Canada-friendly website and the price after taxes $1856.25 and that was the whole kit (pump, hardware and high-pressure return line included. I also had to order a Mr. Gasket 1932 Carburetor "A-daptor kit" (doing my best Johnny Cash impression) for $34.95. It was pricey and not all in-line with my usual MO which is do more with sweat than money. But I have to say the project was a lot of fun. It was nice working with shiny new parts. To each their own but I like it. I'll know more after a second season but - the way I feel now - I'm really confident in the car. I did 400 miles to Edmonton and back in October during a bit of a cold snap and the car didn't give me a moment of concern. Am not advocating it for every application. I have dual SUs on my TR6 and 4-barrel factory carb on the 413 that going back into my 1964 Chrysler project car and wouldn't dream of converting either to EFI. But for what we're asking Thelma to do (be third car for us for three seasons of the year - that my wife can drive without issue) it's (so far) the right answer. And because there was very little info on this when I started down this path I wanted to share with you cats. Cheers.

Ya I had to keep the air cleaner that was important. I had to significantly shorten the rod that held it on and tap new treads but not a biggie. I took the Computer off the side (kept it) by drilling out the spots then filled the opening with a couple of pieces of black Gorilla tape. I actually drafted a new air cleaner decal in Adobe Illustrator that says "Chrysler Fuel Injection" instead of "Chrysler Lean Burn System" but I haven't been too ambitious to replace the original as it's in real nice shape. Maybe if I come across a second one. Cheers.

Beautiful Downtown Roebuck Ont.

Just advancing the stock cam 4 degrees will really wake up the bottom end response. The advertised compression ratio was 8:1ish when it was actually barely in the high 7:1 range which is the real reason the smog motor is such a dog moreso than the camshaft. The stock TQ intake will flow well enough to support about 5800 RPM max which is about 900 RPM past where the stock cam and cylinder head will run out of breath.

Where have you been hiding? Several of us are from the Calgary area here and we all get together from time to time...

Why not put your fuel injection sticker on the other side of your air cleaner- it's a 1 of 1 don't you know you could tell people.

Lol.

Go and meet Graham and the boys and enjoy good company- I came from NZ and you're a local. I had the pleasure of meeting Graham, Bill, Peter, Terry, Tobias and some strange critter who likes cans Derek aka Can Critter. Great folks all who I'll probably see late 2020 as finances will be better by then.

Sweet, I’m always down for a burn. I get out a bit with some Triumph guys but would be nice to roll with the big girls. Pm and I’ll shoot you my email. Cheers,

Yes, it does. I just registered the car for the new driving season last week. We're headed into the third driving season and I haven't had a problem yet.
I found your thread when searching for info re: whether it's better to DIY rebuild my Thermoquad or buy one already rebuilt. My '74 T&C needs help with the fuel system - and

After reading this thread - and looking at my bank statement - I'm really leaning toward pulling the trigger on the EFI for my wagon. The price makes me balk. On the other hand, it's not bad relative to how much gas I go through.

BTW, my parents were born and raised in Winnipeg.

I have a rebuilt Thermoquad if you’re interested.. If numbers matter to you, I can PM pics of the stamped numbers on the body. Let me know

Just to follow up at the end of this driving season (a couple of months back now). I had one problem with Thelma this season. She was starting to stall at intersections and had trouble staying in balance on the tuner. It turned out to be that a couple of Canadian Tire vacuum line caps had crumbled. Replacing those fixed the issue and she ran fine after that. I still am happy with the upgrade on the car. As I said, it's not a fix-all, and I don't recommend it for every application. I am very much a "Leave 'em stock" guy, but I do think the Spark Advance system was flawed from the get-go. I tried to make it work and, before the upgrade, I experienced a lot of frustration. I have Scottish ancestry, so it takes a lot to get me to drop that kind of coin on a car.

That being said, I am probably going to put Thelma on the block this spring. I have had a hankering for a station wagon for the last few years and I really want to scratch that itch before the kids are too old to want to hang out with me anymore. I guess like everyone else I want to recapture a part of my youth and, when I was a kid, big wagons were everywhere. I think the 70s was the height of the wagon era so an early to mid-70s Plymouth or Chrysler is what I am looking for (#fundriver). My wife is pretty understanding but adding another to the fleet without cutting one loose would be a bridge too far - and my TR6 and '64 New Yorker mean way too much to me to ever cut loose.

I'll post it here also when she's ready to sell so you can all take your shots at her ;). But that's still a few months away. Hope you're all well.

I can relate to the wagon thing: When I finally had some extra money, I ended my four-decade wait for a Formal-era Town & Country. (It didn’t help that I was only a grade-schooler when the ’74-’77s rolled off the assembly line.)

I’ve been outvoted by the kids - and my wife on selling Thelma. She’s going to be with me for awhile.
