I have a 98 leggy gt 2.5 I just started getting rod knock I have an ej257 Short block with aftermarket pistons, is it possible to swap these parts around. Looking to track the car and build it up nice, so I understand modification may need to take place. Sorry if this has been asked and answered, I work on tug bots on the Great Lakes and am not able to do some real in-depth searching.
