Awesome dude, all that hard work and you did it YOURSELF.
I wish I had the knowledge I have now back 4 years ago ....I'd have saved a chunk.
So you used the T/A Pittman arm and you were able to keep the GTO alternator stock location ??
I have the fix for the Tach. I just fixed mine. This is if you're running electronic gauges that is.
This is per John Speartech and some guys on here knew about it too.
The signal wire for the tach needs a 4.7K resistor ($1 Radio Shack) T-'d into a 12V ignition source.
Apparently the power isn't enough from the ECM to the gauge.
I just branched my gauges 12V supply into the white wire for the tach.
Now my schematic should show the 12V supply continuing on since I just T'd off it.
Congratulations! It must be a good feeling to have it running. I have been following this thread as I will be doing this in the near future. Sounds like only a couple of minor bugs to work out and you are on the road. Glad it is working out for you.
BTW, the idle sounds great--nice lope. I dont' recall if you mentioned it previously... What cam are you using?
Good job. Great video. You must have mastered the fuel pump setup. I need to look for updates. You could probably make some money with your tank design. Car looks nice.
Ace, I did swap out the pitman around and center link for the drop TA setup. Clears great. So this fix on the tach got yours working? Looks like a run to the Radio Shack
The cam is a Crane 220 dur, 555 lift on 114 lsa, wasn't exactly what I wanted but it was new and I got it cheap and really close to what I wanted (224 dur/ on 112 lsa)
Congrats JJ. Love the videos. I may have to see about finding a TA pitman arm for my L67 swap. Sounds like it'll make things a lot easier for me. And I'll definitely have to remember your fuel tank mods as well
NOw I just have to calibrate my speedo properly. Orange71 posted how to do it here.
Ace, did you keep the tach filter in the circuit or ditch it?
My Tach didn't come with anything like that, so no.
