Hello I got me a engine out of a 90s f-150 and I’m not sure exactly what year but I was wanting to do a turbo build with it and I’ve heard the stock engine can hold it as long as I’m not over 450 hp if I rebuild the bottom end with the stock crank and pistons and rods and do gt40 heads and an on3 turbo kit would it hold together for a while? Or should I find a new block to start with

Smart driving it will be good, tuning is the key (my opinion) to longevity.
I would pay attention to piston to valve clearance if the pistons are the low compression ones, depending on what cam used with those heads.
this is my opinion and not based on actual mechanical ability cept I did have ptv clearance issues with gt40p heads and a B cam on a low compression 5.0 block from a crown vic. Learned a lot with that combo.
