here my question i bought a demon awile ago 340 4 speed 71 motor 4 speed 3.91 gears assuming the motor is pretty much stock. Yet any ideas what qarter mile time i could expect outta somthing like this im gonna run some mickey thompson street slicks too 10.5 inch wide i think havent looked at them in along time.


thanks bryan

14 seconds flat. If you can really row that box, it may drop into 13's somehow, sometime.

Low 14s, high 13 seems about right. If you want to pick up some cheap speed, add headers or a stouter* cam. You'll have to be careful with the cam though - if you go with too high of a lift you'll need to replace valve springs and could have valve-to-piston clearance issues.
Good luck.
