Correct Shift Point

njk53 · 05-02-2010, 01:32 PM

I have talked to different people on this subject and received different answers. Maybe someone can help. For example: Your car has a big block Chevy engine and it makes a peak 450 lb/ft of torque at 3200 rpm and 440 HP at 5700 rpm. The car has a 350 turbo hydamatic. At what engine rpm should your 1-2 shift be? 2-3 shift be?

Depends on the converter stall.

At the RPM that makes the quickest E.T. Pick some shift points and try testing your car instead of talking to people. If you listen the car will tell you what it likes.

Adger, where would you suggest as a starting point? The car is new to us and the previous owner never said where the shift points were. I have been having a hard time getting in touch with him. Car has a 4800 stall converter.

Take Adgers advice, try a few different points. He's right the car will let you know what it wants, that plus the E.T. slip. Joe

With that 4800 stall I would start shifting at 5800 then try a little higher each run until it slows down. Lot of guys are guilty of revving there engines to high, just because it will turn 7000 doesn't mean it is fast there.
