Yesterday I was helping out my neighbor and his son with their car project. It is a 1986 Volvo 240DL Wagon that had an 6.0L LS engine and transmission swap from a Silverado pickup. It was done by the previous owners as a Lemons car build, but was never raced. It has really nice suspension upgrades as well.
We have dubbed the car "The Volvolet."
I helped them replace the cable driven speedometer with an electronic speedo driven from the ECU. The new cluster also came with a tachometer, so I wired that to the ECU as well. I used a 240 ohm pullup resistor to get the tack to trigger off the ECU input.

Found the fuel pressure was low, and traced it back to the hose between the in tank pump and the sender body. The hose was split and bleeding fuel pressure back into the tank. What made it such a bitch to find was that there was no external fuel leak. Once we got that fixed, the car was much happier and way more powerful.
Our next task on it is to install the coolant temp sensor from the Volvo into the chevy coolant passages in the intake so the coolant temp gauge will work.
I actually considered inviting them to Okteenerfest just to see this beast tear up the tail of the dragon.
