Here's both 355 and 383 builds for 87-octane. Easy to duplicate- minimal fabrication required. Builds are identical except for stroke and piston (obviously).

Good quality parts and a well-researched combination makes for great power.
Honestly, there's not much vacuum at idle though. If that's not a big deal, this setup works great!
