Ford guy questions about 429s

[BlueOval Ralph]

The crank was the same between the two motors. There was the S rod motor a very heavy beefy rod, but shorter that the standard 429/460 rod. There was also two styles of boss head; the full hemi chamber (for superspeedways) and the squished chamber.( for the short tracks).

The full hemi was run all tracks at one time, the last time I checked the SK book there wer 28 different NASCAR heads the Boss 429 street had orings in heads NASCAR had orings in block decks
