OK, so here is the update: I rejetted my carb from 74 to 77; replaced the distributor springs with thicker ones; set initial timing to 10*(from 12*); replaced spark plugs with colder ones (r44ts). Engine STILL knocks/pings under load. Could I have installed the distributor wrong? As in, off by a tooth? It idles great, and runs smooth under easy acceleration. Could it be the EGR valve? Confounded and frustrated now! Thanks. JG700
