Hey guys it is my first time on the forum I'm planning on making my 302 from my 69 mustang into a 347 stroker the engine has .040 pistons but a regular crankshaft so I was wondering if I can just get a stroker crankshaft and still be able to use the same pistons?
I'm new this kind of stuff so that part has me stuck because if it is possible it would save me some money.

I suggest calling Scat or your choice crank guy. I suspect the skirt length you have may be too long?

If you got a 351 block and a 3.85" stroke crank you could reuse the pistons. But for a 331 or 347 you need new pistons.

You would need new pistons. Piston overall length would be less and location of wrist pin is different.
