Re: 1964 GMC "crustine" semi-build.
Well I got the box loomed up and wired in. Works nicely! Have some retuning to do and I need to gap the plugs a bit wider, but the engine idles really smooth and it is Very responsive....2nd gear pulls so fast I can't shift fast enough! Will report again and get a video soon. I really don't like hammering on this engine as I am trying to make it last as long as possible. haha Main reason I do these mods is to see how efficient they are.
MSD box: $225(discounted). $249.95 without.
Plug wires: $46 MSD Street Fire 8.0 spiral core universals.
Time: 5 hours installing.
Worth it? Depends on how much you expect. I feel like it gets better throttle response, little better acceleration, starts better, and smoother idle. Also doesn't back fire when slowing down either. Like said, I am sure gapping the plugs a bit wider will help as they come around .035 to .040 and I could push .060 if I wanted to! I did check the spark from the coil to the valve cover.....and needless to say it left burn marks on the paint. haha Not much effort either.
