Car will be out in the next month. Who’s the go to guy to road/dyno tune a Weber 38? It should be close as this carb came with the motor but I want it dialed in. Also can has an AEM wideband. ---

with a slightly similar question, my 240z has dual webers and were never jetted properly. I don’t have an o2 sensor and at the moment I don’t want to add one (need to replace the header etc at some point down the line). How did they tune them back in the day, what was the name of the tool that would go in the exhaust stream to calculate mixture? Curious if anyone local has one of those ---
