Idk if this qualifies as an article but it’s a little known Pontiac fact. My ram air IV SR block that was prepped by Stephens as a back up for my car, had these in it, so I asked the driver of the car. He told me they had special over the counter rods in 69 that were the same as earlier SD rods.
Many didn’t believe this for years but I’ve found a few incidences where they were mentioned. Here’s one example- so “in the know” stock and super stock racers mostly those in the performance division dealer network , would swap out the garbage cast rods and drop these in hoping the tech guys wouldn’t figure it out if the got torn down.of course all Pontiac rods are the same length so 421 and 400 rods are interchangeable These were two reasons not to set records - one it could reset the index and two you didn’t want to get torn down ;-) Last edited by turbo69bird; 01-08-2026 at 06:40 AM.
