Did GM produce any cars with Quadrajet carbs and 200-4R transmissions? If so I would like to use the primary throttle shaft and linkage in the 800 Qjet I have on my 53 instead of the aftermarket linkage conversion. Possible or not?o No: Bob H.
I cant specifically andwer your 1st question because I dont know, but..... I can definitely tell you that Qjets were produced with the proper TV cable arm on the primary throttle shaft arm. I cut the TV cable arm off a Chevy Qjet and welded it to the Stock primary throttle shaft of a 68 Buick Qjet, using the double-D mounting hole to align it properly on the shaft. Works great. See my "200R4 swap summary" thread for a pic of what I did, and some details. I used the stock TV cable and bracket from the donor 86 Cutlass. Actually swapping out the entire primary shaft may be possible, but the shaft length may become a consideration depending on the Qjet years you are using. I have used bronze spacer sleeves (www.mcmaster.com), which I custom cut to the length I needed, to take up the extra space when using a later model Qjet throttle shaft on an older baseplate. Just my thoughts. Good luck. Ken G.
Yes they did, look for early 80s GM cars with the 307 olds and the 200r4. These are 800 cfm carbs but will have to be re-jetted for your combo of course. You likely can swap the the linkage parts, as well.
I went through an issue with the tv cable recently and found this GREAT article about how to troubleshoot TV cable out of adjustment issues. In 10 minutes i had the trans shifting perfectly! http://www.tvmadeez.com/article/index.php
Thanks for the info guys. My transmission works fine but I have a home made bracket on there that doesn't look so good. The geometry is correct I just don't like the looks of it. I'm trying to clean it up a little. Bob H
Bob,you may want to check chevy trucks that were offered with 700r trans also.I would think that the geometry for the tv cable would be very similar if not the same for those.The brackets that support the throttle and TV cables are nice pieces that are secured by the rear carb mounting bolts,are made of good metal and are very suitable for modification(welding) while still retaining a stock look.Let us know what you come up with.
More than likely they were using 400 turbos on the big blocks I don't know if they used 400s behind the small block Monte. The Monte carlo came out in 68 not sure if they had an SS then but my son Darren told me they had an SS 454 Monte in 70. Either way it was before the 200-4R was available. You are probably thinking of the mid or late 80 Monte. Bob H.
I use the carb from a mid 80's GM wagon or other big GM that had a 307 V8 and 2004R trans the carb bracket bolts to the carb not the intake so I use the cable and bracket The carb is also a Qjet so very easy to change the primary shaft as well i have put over 20,000 miles with this set up and works PERFECTLY no messing around trust me this is a great set up Ken email me and i may still have some pictures or i can get some for you kkklassen@shaw.ca
Sorry, I should have clarified. The first year or two of the 2nd (or 3rd) generation (G body) Monte Carlo SS, not the '70-'72 models.
thats correct but the cable and bracket from the 307 OLDS fits on our Buicks MUCH better as it does not use an intake bolt it uses the rear carb bolt holes so less fiddiling around
I got the primary shaft from a mid 80s Riv and put it in my Q-jet. It works fine and looks right.:3gears: :3gears:
Thanks for the replies Buick buddies. It's time for a trip to the junk yard. I will post a picture of my home made linkage and you will know why I want to change.:laugh: Bob H.
Lots of mid 80's GM cars used the Qjet and 200-4R; Their "common" bracket to install on back of an earlier (late 60's/ early 70's) Qjet needs to have a spacer between carb and STOCK manifold, in addition to a linkage adapter for the correct geometry (which is crucial for 200-4R life). Linkage adapter is relatively cheap... Had not thought about swapping out the entire primary throttle shaft...(thought they were step-bored and sealed)???
Have you tried Bow Tie Overdrive.I used one of there set ups when I installed a 700 in my 72 chev PU which has a Holley but they also make one for a Quad.I will send some pics if you would like. Kirk Chandler,AZ
