A trick many did BEFORE aftermarket rods became common, was to intentionally machine the rods wide at the parting line. As the big end of the rod stretches with big rpm/piston weights, the sides pinch in and cut off the oil flow. Making them wide at the parting line helps prevent spun bearings in these applications. I knew a guy who did this on his stock rod 351C engines.vortecpro wrote: ↑Wed Oct 27, 2021 10:17 am Two questions:
1. Is it bad to be big at the parting line?
2. How big is it at the parting line in relation to the spec?
To answer your question I charge 175.00 to resize those rods. Keep in mind balancing the big ends can change the size, depending on how hot they got during balancing.
Personally, I would not worry about the rods being a little wide at the parting line.
Good Luck
