78TA HEI Distributor - Which way around?
Posted: Sat Mar 31, 2018 10:08 am
Hi all
To make a long story short, does anyone know which way around the HEI distributor should go on a 78TA L78 400?
The 78 service manual shows the vacuum advance pointing passenger side, yet the 78 parts catalog has it pointing driver side (see attached images).
Problem with it pointing passenger side is that it now fouls the heater hose connection on the cylinder head, but because my heads are earlier heads I'm not sure if this is why. But seems odd that two official Pontiac documents differ, which still leaves the question open.
Difficult to find any reliable images on the internet or YouTube, as usually obscured by other parts.
Hoping to find a consensus from a few owners just to be sure either way, all help will be very much appreciated.
Thanks
Steve
