blown head gaskets, broken timing chain, wiped out cam lobes, huge vacuum leaks(like brake booster line) valves hanging up or broken/bent, cracked head/block (although youd be losing coolant). Check for milkshake in your oil just to be safe. Just a few things besides fuel and spark. And yeah montes had l69s till 88. I believe every small block changed when they changed the heads over, i could be wrong though. The l69 will fly with a few bolt ons. My camaro had a real HEI distributor(vac advance), a holley 600 or something, performer intake, small tube headers and a few other small things. 5 speeds came with the 3.73s, that combo with the higher-than-normal-305 revving motor, made for a very fun car
