Rochester Carb and TH350
 

Just upgraded from a 3 speed to a th350 and i have an old 4-bbl and what the problem is, is that there is no way to hook up the kickdown cable, anybody run into this?? I eventually want to replace the carb but for the time being need to use this $$

You will need to buy a kick down cable bracket. You can get them at autozone, checker, Summit is good and they are like $10-12. The Q-jet should have a hole on the throtle bracket just below where the throttle cable attaches to the carb, add the correct linkage bolt and you are on your way.

Is it a Q-jet or a 4G? Might just leave the cable off for now, and just downshift with the shift lever. It may upshift a little early at full-throttle in Drive (mine did), but you can hold it in gear with the shifter also, if you wish. It won't hurt a T-350 to run it with the cable unhooked.

Mine is still disconnected, after the P.O. replaced the intake and carburetor using an Edelbrock 1405 (manual choke). The TH400 wouldn't kick down at all. I had the tranny valve body modified for crisper shifting and the shop put in the smallest diameter modulator that would work with a TH400. It's black. So, now the tranny will kick down, but not like I would prefer that it do. Until I get my new kickdown installed, it'll have to do.....like it has for the past 4 years.
