Planning a LC9 swap for 70 C10. Read that LC9 is a truck engine and would have small block chev v8 size connectors for radiator hoses.

Can anyone confirm this? Would save a bunch on buying LS type conversion radiator.

Thanks

 

I thin you mean lQ9, but yeah your old radiator should work. Both heater hoses go to the water pump, you can use the stock upper hose for a 5.3/6.0 engine and it will reach and fit pretty well. I used an adapter to reduce the heater hose outlet on the stock radiator for the steam vent hose from the new engine, this was all on an 82 silverado.
