Does anyone know if the right head also has a threaded port for a sending unit that I could use to add the temp sensor for the EFI?

Brad - That's a nice clean place to put it, and accessible too. Thanks for the idea!

I've been thinking for a while about adding EFI to my 64 R2 and I think I've found a good system from Fitech: The Go EFI 4 Power Adder. https://fitechefi.com/product/35206-go-efi-4-600-hp-power-adder-bright-aluminum-efi-system-with-force-fuel-delivery-master-kit/ One required part of the install is a coolant temp sensor that is 3/8" NPT. I haven't taken the bracketry for the ignition shielding off the engine to get to the coolant sender on the back of the driver's side head...Is it 3/8"? If not, any other ideas where I could install this sensor? Thanks, Tim

Hi Everybody, Like I assume is the case for many Avantis mine has an issue on hot days at slow speeds or when stuck in traffic. The coolant temp will spike over 200 and come right back down once the car is moving at a reasonable speed. I've decided to install a pusher fan on the front of the radiator to give the cooling system a little extra help. The simple way to do this would be to just wire up a switch and control it from the cabin but I figured I'd try to use a relay and temp sensor so it runs automatically during temp spikes. I assume someone (likely a few) have done a similar install and I'm wondering where you installed the coolant temp sensor for the fan. I know the stock temp sensor is in the back of the driver's side head and it looks like there is a threaded plug to match in the other head but both are very small diameter compared to the 3/8" sensor that came with my fan. Advice on where to install the current sensor and/or suggestions of where to find a more appropriate single wire sensor are appreciated! I'd rather not drill and tap anything new if it can be avoided. Thanks, Tim

Hi Folks, When I found my Avanti a couple of years ago I also ended up with this block and need help identifying and valuing it. It appears to never have been assembled and is well preserved. The return address on the shipping label is South Bend so I assume it is NOS or remanufactured but not really sure. I do not have a use for it and would like to find it a new home so it doesn't go do waste. It is block and pistons only, not crank, rods, etc. If anyone can provide information I'd really appreciate it!
