3.23 or 3.55 Behind a 318

Building a 318/349 isn’t cheap or easy. Building 318/390 is easy, ordering the kit is pressing a button easy.

Building a 360 or 400+ is dealers choice with the 360 being cheaper, part selection dependent.

A properly built and set up 360 can burn the rubber and be very quick. It is not a slouch.

You don’t need 400+ cubes.
But you want 400+ cubes.

Bottom line, build what you want. Don’t look back. Enjoy!

Agreed.

Shorter stroke, higher revving (more noise) And I could still lie and say the 360 is just a 318.

400+ cubes is the B block. That's going to be at most a 3.915 arm for a 470, taller compression height on the piston should hypothetically lead to longer engine life over a 451.

I am going with the shorter strokes for engine longevity and lower piston speed. I figure that anything I can do to build durability and reduce potential points of failure is a good thing. Also, the shorter stroke will be better suited to the 4.10 gearing. I don't worry about burning lots of gas. There are plenty of degenerates in the bay area here who drive their Prius ****-boxes and save the gas for me.
