GM HEI

Oh GM HEI, How I hate thee... let me count the ways...


GOOD LORD I HATE THESE PILES OF GARBAGE.

Im gonna go out on a limb and say I HAVE NEVER had one work right.

Two dead out of the box from summit in a row and now one more that wont time.

The one im referring to now is not new. BUT i have seen this exact same issue in these distributors before this.

This one is 8 deg at 850 RPM and FORTY NINE AT 3,500 RPM....

im gonna look deeper at it tomorrow most likely but I already know how to fix it.

MSD probillet and 6AL. DONE. NO MORE TIMING ISSUES.


Has anyone ever had a GM HEI that worked good?
