or...... if the crank's not ground yet then consider a 4" stroker kit to put under the 360 heads. 390 cu in sounds better while you're doing it than 318 and it's all new too.

Already have a machined crank and rods, as well as the heads. Had an entire rebuilt engine but the block was bad. Long story. Starting with a new block and this opportunity is sitting on the shelf at a reasonable price.
