I'd love to see dyno sheets of all these pump gas, stock stroke, iron headed 383's, with stock logs making honest 425+ HP. Easy? I dont think so...

The combo I posted was never dynoed but it would run 110- 111 in the quarter and at 3860 I am pretty sure it was in the 425 ball park.

Of coarse at 451" it was stock 440 stroke. This was a low budget build with good machine work. Car was street driven and made 100's of pass shifted at 5500. I would not hesitate to build another one just like it.

Getting old just means you were smarter than some and luckier than others.
