318 block and I don't know

@Wayne Rider The idea of putting a 360’s crank into a 318 has been shown here once before. I wasn’t particularly fond of the route taken.

The build starts with cutting the 360 mains down to fit the 318 block. Stock rod length is used. Now comes the hard part and that’s pistons. There going to be a custom order if bought new. That equals expensive.

The other thing to do is modify a set of pistons. IIRC, *I Think* the builder modified a 318 piston to fit. Being there normally pretty far down in the hole, there workable for this. The builder had to cut valve reliefs in the piston.

I don’t find this particular build all the advantages or a big fruitful adventure myself self. However, since you seem to have a bunch of parts, this could be a fun build.

Displacement is 343 on a standard bore & 349 @ a .030 overbore.

Are your pistons notched?
