18,000 orig. mile 318 build

Ok guys i havnt touched the motor yet but did get a good used eddy performer intake and a like new holley 600 from my buddy. But i might hold off n just build up my 318 outta my 75 d100 over the winter n jus keep my current one for a spare. However i do need to get a new set of tires because i burnt my old ones off....lol Jk but my current ones are dryrotted from sitting. Currently it has 195/70r14 all around. I wanna keep with a sleeper look but would like to go alittle wider in the rear but also a street tire thatll work nice on the street and little strip. Any ideas? What do you guys run on your cars?
