My building experience comes from mud racing old domestic vehicles and playing around with making things carry extreme loads or climb stuff not so much go fast but alway go in every kind of weather in and on all kinds of surface including swamp roots an beaver ponds and logging donkeys.
my most recent was an 95' 4X4 S10 V8 conversion 350 ci full race cam 0.60 over ported an polished dyno'd at 485 Hp @3800 rpm with a stage II 4L80AOE set on 37" straight line aluminum rims and I kept the AC cruize power steering all intack and fully function without cutting out the wheel wells I still mintained 190* in grid lock traffice a 110 degrees in the shade all day long roseburg state fair if you have ever been you know and remember the traffic jambs. just a little brag.

 

You make some sense, I put the right length of bolts back on the pressure plate so it's not that. I left the throw out bearing to the tranny cause a friend had told me to leave it in the tranny and to not put it on the pressure plate. I put everything new so idk what could be wrong with it. I wish I had a lot of extra time to do what your telling me to pull out engine and tranny and test it all out but I don't. :\ I have a new born I work and go to school so I don't have much time for it. I feel like just replacing engine and tranny later I want to milk it till it goes out. I'm gonna get another car then I'm going to have this truck as a project
