carb swap???

Postby 85GPLef41 on Fri Nov 14, 2008 10:59 pm

Hello, Im a newbie i own a 1985 GP LE and i just pulled the old 305 for a targetmaster 350 with 30,000 miles on it and i am running into some issues which i hope you guys can help me with. I put on a performer intake with a 1405 carb and im having issues with the tv cable and throttle linkage. Should i buy one of the universal throttle bracket? Can i use the factory bracket?
Thank you in advance for any input

Get a different bracket from jegs or summit. They are designed to adapt the TV cable to Edelbrock carbs to keep proper line pressure in the trans.

Thanks i will call them for a part number so i can order it. Will the lock up converter work if i disconnect the the carb and distributor and use a vacuum advance distributor? Most of the wiring harness still is intact or should i get a lock up kit? What are you running? thanks a bunch

The lockup converter should still work, but i am not positive. I have a lockup kit on my 200-4R but i eliminated my ECM. I am running a complete TV cable kit from Bowtie Overdrives. At the time i put my 200-4R in the simple brackets from jegs were not available so i spent $200on the complete kit to make my TV work with my Holley carb.

Cool thanks do you think the trans would survive behind the 350? The 350 has Edelbrock carb and intake, Hooker headers with a 2.5in dual exhaust sytem .My car also has a rearend out of a 86 Monte SS with 3.73 gears. The engine as far as i know is a stock targetmaster crate engine so i dont know what cam it has nor the compression. the trans is out of 84 Oldsmobile Delta 88 and i just want it to last till i can get it rebuilt.

Yes get the cable geometry correcter. It should hold up behind your 350 as long as its not abused. Change your filter and make sure everything looks ok. My 200-4R is mildly built with a good shift kit and it survives behind a stout 383 that i run hard. I also have a 3.73 geared rear out of a MC SS that has held up so far, but i dont run slicks or go to thedrag strip.

My bad but i need a part number for the cable geometry corrector and the bracket. I didn't get a positive answer from the speedshop when i called. Also i am looking for a air cleaner what are you running? I am looking for a smooth chrome air cleaner but am unsure if i need the offset, centered. or raised base. Again its a 350 with a performer intake and a 1405 Edelbrock carb. just can't seem to figure this out :lol:

wat is a geometry correcter. i have a 200r4 now but i'm replacing it with a 700r4. my 200r4 has been on a edle 600 card for bout a year now. now my trans seems like it doesnt have passing gear any more. i never put or used the after market bracket. would that have messed up my trans

Yes it could have. Improper line pressure can kill a transmission in as little as a few miles. This is one of the reasons I recommend a 1976 or newer Quadrajet and the proper GM bracket for the cables. It ensures that the geometry is right without the expensive correction kits. BTW, I have run an Edelbrock 600 on my 355 before, and yes it does screw up the TV cable geometry. My TH 200 4R is out to lunch now (was a little bad before the Edelbrock carb) and will soon be replaced by a T-5 5 speed manual swap.
