So I grabbed a 2000 5.2 to build into a modest 500-550hp turbo motor to swap into my 88 D150 pickup. It was free, and was a strong runner till it sat in the rain. Since I need to install forged pistons, and oversize valves, I am not too concerned about the bit of corrosion inside. This will almost certainly be a blow through carbureted setup, with the carb inside a box, for ease of tuning. I will be shopping for forged pistons and a fairly modest cam, with 112-114’ish lobe separation. the motor has about 200k on it, so most likely new roller lifters are in order? Any suggestions?
