Ok, here we go again. But I'm wandering if there is a way to calm down the torque on a 406 for a 1/4 mile dry slick. I would really like to have this motor in case I go to diff. tracks. it will be going on a 79 Cutlass 3200lbs, a KP 2bbl roch, 461 heads and stock ex. with 3.73 gears with a powerglide in low. All help will be appreciated! Cam choice, timing, etc. I run in Colorado, and am a lone wolf, so any secrets are safe to pm me. Thanks, Race

You mentioned cam choice - and that can really impact low-end torque, but then you said "in case I went to different tracks" - that implied that you wanted the torque at the more hooked up tracks - are you willing to swap camshafts between tracks?

Otherwise about the only quick things you can do is reduce timing or delay when the advance comes in, or install a gear to keep the engine out of it's power band. Can also play with valve lash...

Ive allways had plenty of motor at quarter mile tracks and not enough tire.

I learned really fast that the thing to adjust is your throttle. bolt the pedal end on 2.5 to 3 inches lower at the smaller tracks. It will slow your throttle pedal ratio down. if youve got an aftermarket pedal with the holes I actually added one more below the lowest one.

I was setting ft my first 3-4 times ever on a quarter but smoking my tires off around cars. An old fart told me to move it for the main, I thought hmmm ok, and won easy for the next 3 weeks in a row, there was no way to slow my foot down that much especially when a car got next to me.

On a side not at my regular half mile track it helped too I could jump on the gas as fast as I could and didnt get loose it was really cool. I moved it up a little after that on halfs.

If you are running headers, larger tubes will kill the torque.
