Kickdown

Ok, I have a 351W (swapped out old 300 I6) with an Edelbrock 600 cfm and a C6 tranny. My problem is when I drop the hammer on the gas, my kickdown drops me into 1st gear. The first time I did this, it instantly went into "warp drive" (5000 RPM) and scared the pants off me. All I wanted to do was hear the secondaries on the carb kick in! Is there a way to adjust the kickdown linkage?

Hey Steve,I can't remember if you had gotten the brackets and hardware to match your carberator.They are available through Edelbrock if needed,but if you've got it hooked up already,just bend or adjust something to where when your carb is wide open,the downshift rod is just bottoming out also.Just for knowledge,did your trans upshift into 2nd after the engine reached 5000rpm? If so this could of been normal,depending on your foward speed before you mashed it to the floor.I think an adjustable modulator can decide throttled downshifts also,but only from 3rd to 2nd,depending on the adjustment.By the way,were you impressed with the power when she revved up like that in 1st and did she pull good in 2nd also{if you kept your foot in it}?

Great power! Yes, I did get the Edelbrock adapter for the kickdown. When I punch it down about 3/4s it kicks into second and really hauls, that is once I get it over about 2100 rpm. I've got a 2000 rpm stall convertor and when she hits the right rpm, it's like igniting the after burners. When I get her broke in (another 6-700 miles?), I'm going to take her over to the high school parking lot, rev her up with the brakes locked and in gear to about 2200 rpm, and drop the hammer to see what type of streaks she'll leave.

Looks like I need to either bend the kickdown rod itself, or the piece that it connects to on the tranny end??

Thanks,

Steve

I know the original carbs had an all threaded screw that would actually push on the rod after a certain amount of pedal travel and that was the fine adjustment point for the downshift rod.Does your Edelbrock have such? I've have seen Holley's with them also.

Oooh! I remember, there is a screw in the carb linkage. I just thought it was for helping to set idle speed, but I'll bet it's for the kickdown! I'll check it out this weekend and let you know.

Thanks,

Steve
