as an auto mechanic who worked on a fleet of vehicles with the 4.3 and 5.0 and 5.7 vortec motors
ALL of them had engine skips within 1000 miles if any plug or ignition component was used that wasnt a/c delco
i even tried a parts store brand cap in my personal truck and it was skipping within 100 miles took it out and there was carbon tracking EVERYWHERE on it
its not worth doing more than once for the pennies you save get a/c delco stuff
