I think the 318 is just fine to build.
It’s only OE stock short comings are low compression, small cylinder bore and small head ports.
Low compression can be fixed if one was willing to go there.
Heads can be ported or swapped.
The smallish cylinder bore isn’t the end of the world.
It’s just like every other engine.
They can run and run well.
IF I was to do one again, I’d shoot for the biggest bore it can safely handle. Then just have a go at it.
