    I just bought another K5 today =)... One has a 700r4 and the other a 350 turbo... My 84 has a built 383 stroker and I drive her everyday... I cant live with out the overdrive... My question is, what can the 700r4 hold(strengh) and what can I do to make it stronger by not killing my wallet??? Should I keep the 350 turbo in her?
    The 84 has 4" of lift and is on 35s(soon to be on 45s)... what should I do?

    you can make a 700r4 handle 700 horse, but it is like $2000 to do so. your best bet would find a 4l80e and get a controler and swap that in.

    you say you HAVE to have overdrive? then why not do a 5 speed swap?? or have a performance built 4L60/700r4 installed.. 4L80e's stock can handle massive amounts of power...

    Yeah, It will cost to do a 700R4. I wanted to do one when i put the Big block in my 73. Really wanted the Overdrive. My tranny guy, who's been building my race tranny's told me about 1600 with NO converter and wouldn't promise anything!! It's not the Horse power, It's the freakin torque that kills them. basically a Th350 with overdrive. The 4L80 is a 400 w/overdrive. (I know, not exactly, but in comparison) So I have a TH400 in it. I could afford that!

    An 87'-later th700R4 is just as strong as a th350. I would just have your 700 rebuilt by someone that knows what the hell they're doing and you should be fine. A built 700 runs around 1,500 to 2,000 bucks.
