Kick down on 68 318/727 charger

[Sheriffandy013]

My kick down does not appear to be working correctly as the car shifts too early. I believe this was originally a 2brl carb but is now a 4. I read some where on a big block when switching from 2brl to 4 that the kick down lever would not work. Is that the case with small block as well? Any suggestions about how to start?

When converting from a 2 bbl to a 4bbl the kickdown rod and carb linkage are moved farther forward on top of the engine. This makes the kickdown rod too short. Needs to be lengthened. A short section can be welded to the rod. If you have the 3 section type of linkage it is sometimes easier to convert to a "Lokar" cable kick down kit.

I like the bouchillion kit. It's pricey but easy to adjust and robust.

I believe this was originally a 2brl carb but is now a 4.

If the 4-barrel is aftermarket, you need the Mopar throttle lever extension and a longer top rod to make the linkage work correctly.

I installed the Lokar cable set on my Dodge 360/727 and have never been able to achieve correct upshift and passing gear operation with the same adjustment. Where can we find said throttle lever extension?

Here’s one for Edelbrock carbs, they have one for Holley carbs as well...
