These numbers-matching Ram Air IV, 4-speed Pontiac GTO's and T/A's are EXTREMELY rare due to the fact that a missed gear with cast-iron connecting rods usually had disastrous consequences. Every single Small and Big Block Chevy had forged connecting rods and it's a shame that Pontiac skimped in the rod department. It sure would have been nice if they had released those famous SD 455 Forged rods just a few years earlier. It would have saved some rare Pontiacs!Hey, does anybody know the story about the theft issue that occured with these forged SD 455 rods when they were released. They were big news and demand was high.

Yes, the bottom end of the Pontiac engine was always prone to breakage. That being said it also makes a numbers matching RAIV car all that more desirable.
