Double ground question...
I have a ground that is located at the motor mount passenger side... I also have one that is bolted to the master cylinder and then to the intake manifold... Is this second ground necessary? Thanks! Also, is this second ground location (72 LT-1) with Air...

the factory ground is in a location which makes it too hard to check the integrity and tightness of. I found the connection on mine was poor due to dirt grease rust and was leaving me in a lurch. Connection was just good enough to run accessories but not crank the engine. So i attached another ground cable from the frame to the front of the head accessory bolt location. Haven't had a problem since.

).My '74 doesn't have a gnd strap on the MC but i verified my block connected to frame with a large cable on p-side mtr mount and checked continuity with ohm-meter.
An extra gnd strap to or from the intake can only help and connection to the MC ensures the pedal assembly will be grnded - as there are pedal mounted switches down there.
Ok, story time. I met one owner who discovered his whole dash lighting was grndd through his dist pwr lead and melted it. Also have read of someone missing his block gnd and the eng reached frame/batt gnd through the u-joints. As car speed increased so did the strobe effect on headlights and interior lighting.
Hope this helps. cardo0
