I got a 93 2.5 245 carb that has been run to death. put rings and bearings in it, Raced it 2 years and still has good leak down. This motor has Mahle's in it. I have seen guys put Wiseco's in and not get the motor broke in before it ate a piston, I have also seen the Wiseco's last. Wiseco was suppose to have went to a top locator pin to eliminate failure. I do not know if they did or not. I know most everybody that races use something other than Wiseco.
