So, everything up top fits...
All the changes and new parts ended up playing pretty nice together. Next up, wiring...
I'm looking for a spark plug recommendation. Specs for the engine call for a AC Delco MR43LTS which I've used before but they are a pain around my headers. Recently I ran a NGK R5724-8 which was nice because it's shorter and easier to get around headers...but it is not available in resistor which I now need. Because one is a "marine" plug and the other is a "race" plug, I seem to be running into dead ends trying to find a shorty resistor plug. Heads are GM Fastburns. Any suggestions?
