14g wire should be OK for 20A at 15' - although to be fair I'm not exactly sure what the color codes mean in this table: 12 Volt Wiring Tech: Gauge to Amps | Offroaders.com
Engineering Toolbox shows a much larger wire, though - 10g @ 15', 20A:

For short term...
Once upon a time, there was a MP single-plane manifold to convert the beer-barrel to something more performance-oriented. I think the carb-only setup in the Summit link above is similar, but the one I have is set up with what appears to be an old-school LA thermostat housing location. This...
I don't have a fitech system at the moment, my EFI is a multiport system but I'm interested to see if one of the issues I'm experiencing could be related to something other than the control unit. Before I ditch the work I've done to put that system together, I want to be as sure as I can be...
Interested in this as well - I'm considering the Command Center as a better way to deal with my fuel supply... I'm currently using an external lift pump to feed an external FI pump. Although I ran a new 3/8" supply line, the return is the original 5/16" line. The return is plumbed in to the...
Circling back on my previous advice while this is being discussed, I have to say that I'm pretty sure my ballast resistor is gone, but I managed all my wiring & install chores back before my #1 Son was born... in 2005. I need to see if I can verify what I remember with what's actually on the...
I think the stock ignition switch will work OK - I was worried about the same issue when I did my GM TPI conversion on my Valiant, and the switch generally operates as make-before-break... that is the ignition circuit is made before the power is fully pulled over to the starting circuit...
Subscribed with a bump... I'm about to pull my existing ECM (GM-based TPI from Affordable) and replace it with SOMETHING that self-tunes. Between kids and life, I just don't have the tinker time any more, and I've got to get my Valiant back on the road soon. I really only need the ECM and...
How do the new heads compare to the old ones? Did MM flow them when they rebuilt them, or did they have some baseline numbers for the spec porting job they did? I know a bunch of folks have flowed RB heads over the years, but it's been a decade since I paid attention to those numbers...
