my chinese hei adjustable vac advance blew out after a year. Swapped it out with this one and its good to go again. The data sheet it comes with explains very well how much a turn of adjust makes

I installed this on a 1957 Chevy 210 with a 283 V8 and HEI distributor. The ability to adjust the vacuum advance was helpful in fine tuning the idle and overall performance.

seems to work fine, .. set it mid-travel & fine tuned from there for 36 deg. max advance...

I had a problem that I couldn't find on my 1978 corvette. It had plenty of power at full trotle but 0 power at cruising speed. I've change the vacuum advance and it resolve my problem.
