1968 GTO 428 engine

[GTOHunter]

I'm thinking that years ago Royal Pontiac would do an engine swap in the GTO's with the 428 engines,and some of the Big Full Size Pontiacs had them also...as MrPbody mentioned the GTO's didn't come out with them from the Factory but Royal Pontiac was affiliated with GM/Pontiac and any GTO fitted with the larger engines were pretty Rare and I believe they were fitted with the Royal Pontiac decal/emblems too!Some early Pontiacs also had the spoked Hurst Rims which were very Rare also!

If a GTO Owner had trouble with their engines or ruined the engine block while they were under warranty the Car was then replaced with an engine that showed SR (service replacement) block!

In 1969 the Ram Air III engine with an automatic had #62 D-port heads and the manual transmission cars had #48 heads.They also had Ram Air exhaust manifolds and ram air induction system in the hood/scoops and intake.The Ram Air wasn't used on just the special Judges....several regular GTO's could be ordered with the Ram Air package too!
