Clean truck !! I have an 86 C20, same color. I replaced the TH400 with a 700R4. I just pulled out the original 350, it only had 165hp. I spent my kid inheritance and got a GM Performance 350/357hp. It’s too heavy for a hot rod, but it should run pretty good. That 700r4 made such a difference, it cruises at 70-75 very nice now. Around 2000-2100 rpm. You have clean vehicles. It’s cold and snowy now here in CO.
