1962 383

Back to the 62 383 question.
Think that's the change over year from 361 to 383.

Same block casting different bore size.
All 383's are the same, steel crank blah, blah, blah.

But the heads are the things that change all through the years.
Early 516 heads have different exhaust port sizes, some small, some BIG!

Very flat intake port and then along comes the 915 in 1967, well its the bees knees!
Every thing else after (and before) in iron wedge head is scrap metal (except MW of course).

You can stroke it, but for me a low deck stroker has to be a 400!
Find a 230 block and its a 1000hp all day long.

Avatar Dart had 1200hp with a factory 230 block...:mob:
