Back to basics methinks with a 383 engine.
The Mopar '516' wedge head was designed for the 361 and 383 engines.
It ended up on the 413/426 and then the 440, after the max wedge era.
It was never enough head for a 440 and is more suited to a 383.
In 1967 the infamous 915 was produced to correct the failings of the 516.
The 1968-906 and later heads are all SMOG heads up too the 452.
How much more rpm can a 383/400 low deck take over a 440?
We revved our race 440 to 7200rpm and it stayed together for twenty years.
Are we thinking a low deck stroker can take it to 7500rpm or more?
Light LOW-deck engine in an A-Body, anything else B/C body needs a 440 stroker...
