I have a LQ4 out of a silverado HD thats going in my car. im converting it to a carb setup with a 2216 cam and springs. i also plan on putting a 100hp shot of nitrous on the motor for straights. i keep hearing that i should go ahead and replace the rod bolts while i have the pan off. ive always resized rods when changing bolts but i hear that i dont have to resize these because of the fact that they are powder metal rods. can anyone verify this or give me their insight on this topic?
