Safe rpm

Wrong question.
Should be something like;
I have a street340 with a 727, and peak hp at 5400 rpm. What would be a good shift rpm, to strip it at?
That is answerable in one line.
The 1-2 is about6500, the 2-3 is about6300, trap is about5700.
Yes you can short shift second.
I would short them all and then what YellowRose said;shift loops

Each gear will be different. Why? cuz the splits are different. The 727 ratios are 2.45-1.45-1.00, and the splits are 59%, and 69%. To center your HP peak, such that the outgoing hp is equal to the in-coming hp, the above shift points are sorta guessed at. Most times the power drops off faster, after the peak than it rises up, to the peak. I arbitrarly chopped 300 off the 1-2(6800), and 100 off the 2-3(6500). and YR likes 300 over the peak to trap.

But really what is the safe rpm?
Buy a good tranny blanket and find out!
Ok that's bad. I have been shifting my 3.58 stroke 360 at up to 7200 for 15 or more years and over 100,000 miles, cast crank,stock 340 rods, KB 107s, A-833
Your 3.31 stroke forged crank? same rods, LIGHTWEIGHT pistons, should go higher.
There is a formula based on piston speed.I don't have it.Anybody know it?
