Transmission shift points...

[xtreme80]

I'm not too familiar with transmissions at all, so bear with me on this one.

After installing my tach, I'm finding out that my engine is shifting at WOT at 4200 rpm, which is about normal for a stock engine. Well I've got a crate that states it will make it's peak power at 5200 RPM. While I don't want the engine running that high, I'd like to bump it to where it would shift around 4800 or so instead of 41-42.

From what I remember this can be accomplished by making an adjustment on the transmission right? But what kind of adjustment? When I adjust the kickdown cable with more slack, it will shift sooner, but I've got it adjusted back as far as the bracket will allow. Without buying a different bracket, does anything have any suggestions on how I can get the engine to run a little higher up?

Thanks!
