For best acceleration, you shift approximately 500 RPM above the HP peak.
That's 6800 RPM for this engine. Given the 3.75" stroke, that's the
equivalent mean piston speed of 7000 RPM in a stock stroke 351C.
That's sporty for a street engine but as long as it pulls well in your
normal operating range, shouldn't be a problem. If, as I suspect, your
engine was tested with dyno headers and no mufflers (or efficient ones),
your engine, as installed, may make less power at a lower RPM. Typical
Pantera mufflers can lose 50+ HP on an engine like yours.
