rpm shift point in relation to hp

not sure if this is engine tech or trans tech kind of both

my engine made peak hp at 6300 rpm , with a powerglide were should my shift point be in relation to hp
currently shift point was 6200 Rpm and went through traps at 6800.


Im curious if i should be shifting past peak and figuaring if there is any shift rpm loss



long off season in the winter up here thinking of a lot of stuff lol

From my past experience the shift point won't change E.T a whole lot.  Basically because the car doesn't stay in low gear long enough after launch.  The E.T of the car is going to be more determined by the tire size, gear size, and converter with any given engine combo.  Make sure the converter will stall about 200 RPM above peak torque chip removed and on the floor with transbrake on!  When that is right now you play with chips (launch RPM and shift RPM).  Car will go through the traps at RPM determined by same things (tire size, gear size, and converter).  Happy Tuning!

My 532 TFS street head rons alky injected I shift at 6200 traps at 6500 with 32X14X15 tire and 4.88 gear. 5.47 best E.T.

I think a lot depends on your dyno sheet. if its stays close to peak hp keep it reving, if it falls off right after peak, shift at the start of the drop. I think its conunter productive to shift before your peak hp. Best way I can think of is try. if you feel it nose over or stop pulling, you missed your shift rpm.

To what RPM does it fall back to...?
It should stay well above the TORQUE peak RPM. Shifting just barely after peak HORSEPOWER is usually best .
