i have an 88 s-10 with 2.5" body lift and 33/12.5/15 tires. i did not build it this way the previous owner did this and did nothing else. what i want to do is:

tire that does not rub frame / thinking 32/11.5/15 ??? will that clear???
bigger engine / 350 small block????
custom dual exaust / what size pipes for a 350 non-blown?

what is available for a beefier manual transmission and axels?
what needs to be done to beef up this truck to handle this kind of work

im just kind of interested to hear some ideas of what all my options are and what could be done...
