69 ZL2 Coil Bracket: How to ID?
« on: February 25, 2006, 10:42:31 PM »
I would like to see a nice picture of the proper coil bracket for a 69 ZL2 option.  I have a SB 350, but I don't think that matters?  I would like to know what angle the coil makes with either horizontal or vertical.  I have a bracket that places the coil @ a 25 deg angle from vertical.  I think that this might be the standard bracket and not the one that I need.

Thank you,


JohnZ

Here's the original ZL2 coil mounting on my 02D Z/28.  :)

For whatever it is worth the ZL2 coil bracket is the same one used on the 275/327 engine 66-67.
Learning more and more about less and less...

Hey JohnZ!

What's with that plugged off vacuum advance line?  Looks like the SMOG pump diverter valve isn't functional........

That's my "driving" setup, with full manifold vacuum (from the tee in the choke pull-off hose, which normally feeds the diverter valve) to the vacuum advance can; for "show", the cap comes off the end of the original steel line, the original short striped hose to the vacuum advance goes back on, the long piece of hose comes off, and the (plugged) diverter valve hose goes back on the choke pull-off tee.

The factory setup used "ported" vacuum to the distributor vacuum advance as an emissions "band-aid" to retard idle spark timing to increase idle exhaust gas temperature to improve the "afterburn" in the exhaust manifolds with A.I.R., but it also caused idle instability, idle and traffic cooling issues, and poor throttle response. Doesn't take much to fix it.  :)

Thanks for the picture John.  Here is a picture of my setup where you can see how much my coil hits the air cleaner.  I have the stock cast iron intake and Rochester carb 4MV.  I don't have any spacer between the carb and intake.  I also have a 2 1/8" tall ring which moves the seal ring up 2 1/8".  I'll also post a better pic of just the coil bracket.

Here is the other view of my coil bracket...

Thank you.
