Installed a HEI system on the "62 C-10. It"s the large cap GM type. Tight fit with the Push Rod Cover but it does work w/o modifications. Started right up but haven't put a timing light on it yet. Install was straight forward and only took about an hour. Will put some road miles on it Saturday so we'll see how it performs.
