go for it
Shawn,
I have the 98 12v with the auto and 3:54 gears, so our trucks are similar. I went with the 250 hp tst plate and here are some of my findings.
While installing the plate, the break-off screw is a bi... ch to get out. Invest in a good impact driver to do the job. I personnaly stripped the head with mine and had to apply tanginal force by tapping the edge (for about 45 minutes) to get the screw out.
Watch the video, read the directions, call me, we can do it together. You buy the beer.
Many warn of the increased power effects on your transmission, but with over 70k miles on yours, I would be looking to up-grade to an aftermarket TC and VB and update kit from DTT ASAP anyway.
I didn't want to waste time gradually moving up the torque plate tree, so I passed the 230hp plate and dropped in the 250 and love it. One has to be mindfull, however, of the capabilities of this motor when BOMBED and apply the power smoothly while running a slushbox auto---even when stock, if you want things to last. (the transmission)
My advice,,, Get the guages first, Period. Get the plate, save for the transmission upgrades.
Give me a call at Station 10 on Tuesday the 18th. We can rap.
Steve.
