Well, I figure I will start a thread to show what I have done to my 1978 Suburban so far. I will post pictures as I can, and just FYI, this truck is my ONLY car/truck and is my families daily driver/trail runner/do every thing truck. I am building this truck slowly, while trying to support a family of 5 on less then 2000.00/month income, so I guess I am doing pretty good. When I got the truck, it was totally stock with a 350ci, SM465, NP205, 10b front 12b rear axles with 3.73 gears, and 265/75/16 tires on stock steel 16x7 rims. The first mod I made was to add 33x12.50x15 All Terrain tires on stock 15x8 rally rims. I didn't like the stock bucket seats that came in my truck, plus they where two differant colors so I changed them to a set of APC Super Sport seats, but didn't like them either, so out they went, and in went a set of conversion van captain seats plus a blazer center console. The next thing was to upgrade the exhust some. It had a 2.5" single tube exhust with a "turbo" muffler. I changed the muffler to a single chamber 2.5" MAGNA FLOW muffler (single in/dual out) with rear exiting tips. This mod was brought on after the original muffler fell off while driving down the hiway . The next thing I did was to replace the clutch after distroying it in the mud, I replaced it with a HAYS clutch. the shop also replaced all the u-joints on both driveshafts as NONE of them where reusable.....YIKES! Next I got a deal (?) on a home made WARN classic looking bumper, paid $50.00 and my stock chrome bumper for it....now I need a winch to go in it! Next came new tires thanks to some Jack A$$ who sliced my tires at a local resturant, so I went with a set of four 35x12.50x15 Dunlop Radial Mud Rovers. These required some fender trimming, and sence my truck had LOTS of Chevy rust around the wells, I trimmed ALOT of metal away. I accually have room to totally flex my stock suspension with out rubbing the tires at all! I also never liked the stock plastic grill on these trucks, so I made my own out of a peice of expanded steel, and I also mounted a set of HELLA 500 lights behind the new grill, to protect them from rocks and tree branchs. I have also added a stereo system, althou it is a bit differant from most as it has NO AM, FM, Cass, or CD player. It consists of a XM radio (Sports caster) a 5 band parametric EQ, a Memphis Belle amp (75x4 plus 1100x1 5channel amp) and then out to two sets of Memphis SQ6.5s (6.5 mid/1" tweet w/crossover) and two 12" Memphis subs in a sealed box (wired at 1ohm). I have a 2" EZ-RIDE lift kit on the way, and also plan a few more off road lights, a 9000lb or larger winch, and maybe a Dana60/14bff swap. If I do the axle swap or not, I will be upgrading to 4.56 gears and a rear locker. I also plan on a O.D. Green with flat black trim paint job in the future.
