Episode 362 of Finnegan's Garage is full of super nerd engine tuning information. We used a Racepak IQ3 data-logging dashboard to record the information from 10 different O2 sensors mounted in our headers to find out how each individual cylinder of the 632ci Big Block Chevy was running. We then used the info to make adjustments to a pair of Holley Gen 3 1,250cfm Dominator carburetors mounted atop a tunnel ram intake manifold. The results were stunning!
