Double checking, block drains on 454 Crusaders

[Mike Dzurko]

1991 Crusaders 454 raw water cooled. Found and drained the blocks on the port sides of the engines. Could not find drains on the strbd sides? Did find a sensor in the area on one engine, can't get to that side on the other engine. I've read here that you just need to drain one side . . . will be filling with antifreeze from the thermostat . . so I'm just checking so I can sleep well this winter Thanks!
