i have a problem with a bad case of bucking during cruise below 40mph between 1200-1900 rpm. and during deceleration in a smaller rpm window. i know it could be a number of things but i want to know where to start.
1. clutch. i have a new zoom 10" clutch
2. driveshaft. i have changed out the dampend yoke for a non dampened one to shorten the driveshaft 1/4 inch ( went from a 7.5 to 8.8 rearend)
3. control arm bushings. i have the stock style ones in the car.
last winter i changed from a stroked windsor to my old 347(yes i know a big downgrade but i wanted a dd instead of a race car). installed a brand new t5z. and changed the gears to 3.27.
where would you guys start?
