Like everybody said, the early small block WP and cover will bolt up directly to the 340.

I've bolted up my '68 318 timing cover and water pump to my healthy '74 360 installed in my '68 B'cuda. I am having problems running hot with my 2 core 22" radiator in weather over 70*. To attempt to combat the heating, I'm adding a deep pan with cooling tubes to my 904 to help shed heat from the 9.5" convertor (literature says the pan can shed up to 20*) before it can get to the radiator. I have high oil pressure right now running 20w50 Rotella, so I'm going to switch down to 10w30 and ZDDPlus to reduce some heat there also. Last move would be to replace the water pump with a HP unit with a disc attached to the impeller to reduce cavitation. If none of these 3 work, then I'll be looking at an aluminum radiator. FYI, I'm running a 22" shroud off a /6 (mounted upside down with minor mods), and a 5 blade viscous fan presently.
