I am very confused about what exactly is going on with this car
I have a decent amount of mods and ive been trying to find the source of this for awhile now
The car is running slightly rich but thats another day and story with the lt1 edit
Throughout my changeover I have always had this bad vibration at 4500rpm
I had the car dynoed the other day and right when this vibration starts i don't gain anymore power
I had 310hp 320tq at the wheel on the dyno @ 4500rpm
then it broke up and stopped making power
Could this be valve float???
any ideas guys its vibrating so bad but only at that high rpm????????????????????????????????????????
