I'm still trying to find my 261 engine. I may have found a truck that has my engine but the seller is a bit confused. Does anyone know when the grill changed from the 5-bar to the bull-nosed grill on the Chevy 2-ton trucks? I have someone selling what they think is a 52, but it has the bull-nose grill. Should I believe it is newer than 52? I think it's an older lady so she isn't able to get numbers off the engine for me. Any help here?
