Then sell it and use a cheap core from the junkers to build your stroker. With the difference, you'll defray a helluva lot of the stroking expense. All you'd be using from your crate motor is the block and maybe the rods.
What does a Cheap core cost? I still have to buy a stroker kit plus any machine work on a junker. Not sure if I'm following you. The 5.9L 360 Crate Magnum was from a wrecked 70 Dart. Would stroke to a 6.4L. Where is the defrayed cost?
