I recently bought a bone-stock 88 C3500 454 with 130k on the odometer. I want to make this a really peppy street truck. Something I can beat 4.6 GT's with. Something competetive with all the new trucks. It'll get a good chunk of highway useage so changing the tranny out to be able to go 70 down the highway without this thing sounding like a B-52 would be nice.
Ive got several questions, some of them simple, some of them will require a little more...opinionated an answer. So...herre we go..

1. Engine being bone-stock, can I throw a 700R4 behind it for a little while without having catastrophic failure?

2. Is it a good idea to keep my TBI setup, or should I go with a carb set up? The nice TBI stuff gets very exensive for what youre gaining.

3. I've already made up my mind to take the 4.10 out and throw in a 3.73 but, if I do the 700r swap am I compromising the "truck" at all?

Thanks guys. I wouldnt say Im new to this but, I've worked on 350 TBI engines my whole life..never touched a TBI 454.
