Hi everyone. Sorting out some issues on a 69 I bought recently and have a question about the timing and distributor setup.
I've verified proper TDC, marked it, and the rotor is pointing to cylinder one at TDC, however spark plug # 1 is pointing to #6. I've also triple checked correct firing order and plug wires and distrib are nearly brand new.
The damper also has the TDC and timing markings set up based off of #6 versus #1. The rotor points at #6 after one full rotation from TDC.
Prior owner/engine builder definitely set it up this way on purpose, but is it correct? I thought rotor and #1 plug on dist cap should all be pointing at #1 cylinder at TDC for starting, then timing would be set off of true TDC mark from there. If I set it up with #1 wire facing #1 cylinder, engine will not start and backfires/flames out of the carb. Runs when I face the #1 plug wire at #6 cylinder.
I started looking at it b/c power is still lacking and running too rich after a full rebuild of Holley so started to suspect distributor might be 180 off or something. Timing definitely doesn't seem right but wanted to check before pulling the distributor since I don't know Chevy motors that well.
