Ok so the car is a 99 gt gp and i have a question as to why i keep going through motors so fast.
I swapped out my motor and transmission from a gt setup to a l67 with the hd tranny. I did a 3.4 setup with headers at the same time of this swap with a tuned ecu
Now i know these motors are externally balanced via the harmonic balancer and the flex plate . Well when i was doing the swap i noticed the hd trannsmissions touqe converter was in rough shape so i was going to use my gt tourqe converter but this required i use my gt flex plate also i marked were the weiight was on the motor when i swapped the flexplates as too not unbalance the motor but i didnt pay attention to see if there waa any weight difference
I havent goten an engine to last longer then 1000 miles in this car since this swap so obviously something is wrong here and i want to find out whats wrong because im going to try this one more time before i give up on this. I apreciateany help you can give me and feel free to ask me anything im looking at all options right now. I dont beat on these engines and that whats been stumping me as too why this is happening i mean its not like im putting out a crazy amount of power
So i was wondering am i unbalancing my motors by doing this and causing stress on the bearings causing my engines to gernade?
