273 to 340 swap

The 273 probably has the early water pump with bottom hose going to the driver side of radiator. The 340 probably has the water pump with passenger side hose exit. If this is the case I'm thinking the pulleys and brackets might not work on the 340 or at least not with out modification or shims. based on my 273 to 340 swap.

I used the pulleys & brackets that came with the 340 engine
