Was wanting to know what you guys thought was the best location for factory or aftermarket analog engine temperature gauge sender, when the Holley Sniper ECT sensor is occupying the factory location in the block. I have a 400 motor 385 series. This may be similar to what someone has done to their Cleveland 335 series Sniper install. My factory plugged locations available are 2 in the thermostat housing (above the t stat), one in the water pump (colder side). Intake is dry on 400. And yes I know Holley has forums too. Any input would be helpful. Would prefer not to drill any new holes if possible, and I'm not sure if I have block drains yet.
