'67 Fleetwood - Switch Pitch TH400 w/ Edelbrock Carb (Page 2/3) tesmith66 SEP 11, 03:16 PM If you go that route, be sure and insulate the switch. That 12V terminal sticking up naked in the sea of grounded metal is a bit scary. I have a TH400 that may end up in my El Camino. I had a gas pedal switch eons ago, but haven't seen it in 30 years. Always thought about using a switch setup like that, but $50 is just plain mean. Here's a switch: http://www.elecdirect.com/p...ovKhq7gBEiQAEvsBZ_S_ All you need to activate it is a spring. That cable setup B&M uses is superfluous. Of course, you could run a cable inside the cabin to keep the switch dry.

You mean short production run? Also, can you describe the "problem?" I've got a bit of Q-jet experience (from long ago), but I might be able to help. Some of the old hot rodders on here as well may know. If you were going to replace it, why not go with a rebuilt Q-jet or at least another spreadbore carb so you don't need an adapter. Holley makes the 4175 as a Q-jet replacement. You may spend more time and trouble getting that 1406 to work than fixing the original carb or replacing it with another Q-jet. thesameguy SEP 12, 05:15 PM All the carb stuff is in the past - there is a brand new 1406 w/ adapter installed, plumbed, and tuned on the motor, I just need to make it control the transmission properly. It just wasn't worth paying $500 for one of the other options when a $240 1406 does the job just fine - unless a more expensive carb would have simplified installation... which they wouldn't. The 429's Q-Jet is unique to the Cadillac in just about every way except the bore layout. Going 4175 for example would save an intake adapter but none of the other work. It just wasn't worth $260 to save an adapter. Where I am now is a carb that needs transmission control features. And, of course, the switch-pitch TH400 is also a very short-run transmission so there aren't any off-the-shelf solutions there, either. At least not in 2015. I understand in the '80s this would have been less of a problem. If you do know someone who will rebuild a 1967 Cadillac 429 Q-Jet I'd love the name. The best I've gotten so far was from Jet, who very nicely told me I could send it in and they'd see what they could do. Most people just said "Sorry, we don't have parts for that." thesameguy SEP 12, 05:18 PM Last night after too many beers I decided I was plenty capable of making a cam to bolt to the throttle linkage and make switches do things. I don't know how I made it but I did. Unfortunately the success of this operation means I probably just wasted $25 on lever microswitches when I need roller microswitches, but it never hurts to have switches around. I guess I need to work on a prototype bracket to hold roller microswitches I don't have yet... but this is all conceptual anyway. Still, a good drunk effort as far as I'm concerned. Formula88 SEP 12, 05:33 PM At least you'll hone your fabrication skills. Good luck with your project. thesameguy SEP 12, 07:59 PM True enough! Feeling pretty good about the result... https://www.youtube.com/watch?v=GJepufdV1ao tesmith66 SEP 17, 12:36 PM Looks good. Have fun cruisin! thesameguy SEP 17, 02:52 PM I am looking forward to it. I bought the car in 2010 in Denver, CO and drove it 1400 miles back to Sacramento without incident. In '12 I parked it for the winter and when I came back in '13 some stuff was not right... it's taken a long time to clean things up, but I'm on the home stretch. This weekend I'm replacing the old v-belts, a failed exhaust manifold gasket, and hopefully reinstalling the dashpad. After that, I am waiting for remybattery.com to deliver a right-angle battery terminal and some ebay guy in Germany to deliver some Tesa electrical tape. I think that's all there is left before I get some wheel time in one of the best cars GM ever made. 2.5 SEP 24, 12:20 PM Nice car. regarding Qjets I've had good experiences with http://www.cliffshighperformance.com/ thesameguy SEP 27, 12:40 AM Thanks for the tip - I will definitely look into them when it's time to put the qjet back on. In in the interim, I actually put 30 miles on it today, the first time it's been driven since 2013. Took a few miles for the front drums to unstick themselves, but following that not a single hiccup. Felt good driving 5500lbs of American luxury again. Got a few loose ends to tie up but the big work seems to be done. Without the Fleetwood to work on, I'm not sure what to do!
