Check your local speed shop or summit racing. Moroso makes a few different styles that adhere to the bottom of the
oil pan with high temp silicone. They have a regular electrical cord that you can tuck and mount under the car. You just plug it into the wall with an extension cord for 10-15 minutes to get the
oil temp up. It is really easy. The pre
oil deal is more complicated for non dry sump cars. There is an accusump system that you could use which pressurizes the system on start up helping the issue and you can always pull the distributor and spin the oil pump with a drill. I would only do that if the car has been sitting for more than 6 months. It's a pain in the a$$...Good luck
