So I ended up with this 5.3 pushed out to a 383. What could I expect to make horse power wise with this. Where exactly are my weak points. All advice and info would be greatly appreciated. Has anyone done this? Am I wasting my money on this build? I had a nitrous fed (300 shot) 408 stroker last time and got bored with it. I know that my next project will be turbo charged, no doubt. This engine may end up in my ford f250 Built Ford tough, with chevy stuff. Just looking to work with this platform since it is just laying around. Thanks in advance.
