I bought the truck as a long bed with a 5.3 LS already installed but hated the long bed, so what started out as just a short bed conversion went much further than I had planned. I found a clean short bed rear frame and bed and did my conversion. I then decided to go ahead and freshen the motor with a larger cam, headers and and 3” exhaust with Flowmaster mufflers. The 200-4r trans was rebuilt with billet internals and a 3200 stall converter. I also converted to a blazer gas tank to make the exhaust easier to run and moved the battery to under the bed.
