318 La with 360 heads

I’m not diss-ing the 318 at all.

As I said in my first post..... a 350hp 360 headed 318 is easy.
Did it with a 2bbl 30 years ago.

It’s just going to be a higher strung combo than a 350hp 360.
So, in order for that to be what I would consider a successful combo in the car, it should be paired with plenty of stall and gear.
If that’s the type of package the OP is looking for......great.
But if he’s looking for something that works well with a more modest converter and gearing....... then build the motor to suit how you’ll be using the car and don’t worry about the hp numbers.

On the other hand.....a 350hp 360 would be tame enough to have the mild manners and tq to be happy with a mild converter and gearing...... and still end up being 350hp.
