To Tell The Truth,

The whole batch of 'B and' RB' engines had over-rated Horsepower
figures from the factory.

The 383 (330 and 325 HP engines) were much closer to 275 Horsepower.

The 383 (335 HP Road Runner and Super Bee engines) were much
closer to 290 Horsepower.

Of course the 68' 440 cylinder heads, camshaft, valve springs and
exhaust manifolds were worth an additional 15 HP.

The 426/365 HP 'Street Wedge', closer to 300 HP.

The 440/375 HP, still high,,,,,,,more in-line with 360 HP.
