Gotcha. Whatever floats your boat. Not sure if this would apply to your situation but I dropped a manual dohc into an automatic sohc chassis. Once I did this, my car wouldn't turn/crank/spark/fuel pump prime even after I triple checked everything. Come to find out, being that I did not swap the engine bay chassis harness, there was one plug that was by the relay/fuse box by the battery that I had to cut the plug off and twist the 2 wires together. Not sure if this is because the chassis is a sohc chassis or if because it was an automatic chassis. Something you might want to keep an eye out for if the car doesn't want to do anything
