Shift Points How to change?

I have a 1992 Camaro RS with the 700R4 trans and I am currently building a hotter motor, but the stock shift points are at around 5000 rpms due to the original 305 motor. I would like to raise the shift points to as follows: from 1 st to 2 nd 5750 rpm's, and from 2 nd to 3rd 5400 rpms. I do not want to manually shift the trans because I race and I would like to have the utmost consistancy because it is E.T. racing. Is there springs or something that I can remove like the Th 350 or is there more to it? I need help!!!! Thanks in advance.

Well i don't know if your car is equipped with an elect. trans or not but i have changed the shift points on my 700R4 by changing springs and govenor weights. This changed the shift points the same amount in all gears though.

PS: I bought my govenor shift kit from B&M.

Doesn't the chip take care of that? I thought it did, if it does, drop Ed Wright (Fastchip.com) a line at http://www.fastchip.com

Well the part# on my B&M shift kit is #20236 but i bought that kit in 84 or 85 so they may of changed the no. This kit works for TH-350,400 and 700R4. I am still useing this kit. I wrote down the specs. for my 84 Z28 and they are as follows for a 6000 rpm shift point.

Weights = #2 & #5 = 18.4 grams
Springs = Purple & Red

I also made a note that -(1) gram increased the rpm 400. If you had a gram scale you could raise your shift points without a kit. You can do this mod with the trans in the car but it is tight. To make it easier i remove the trans crossmember. Takes a little longer but you can do a better job. I put RTV on the gov. cover just to be sure. When you remove the gov. cover have a small drip pan for a small amount of ATF.
