Manual trans swaps: Cheapest vs Easiest vs Best Performing vs Best Driving Experience

I run at least 20 degrees timing at idle in anything I own (anything that lets me adjust the timing). The more timing, the higher the vacuum and the better it runs. A good vacuum signal down low works wonders in just about any non-EFI engine.

Most factory 10.5" flywheels were around 27-30 lbs so running a 30lbs flywheel is nothing unusual.
