Is there a difference in thermostats between a 37 Dodge and 37 Plymouth? I'm putting a 37 Plymouth engine in my 37 Dodge and noticed the goose neck on the Plymouth as well as the goose neck studs are different (shorter in length) than the Dodge. The Dodge has a taller (thicker) goose neck base, requiring longer studs / bolts. The Plymouth head has studs that I'm a little hesitant to try to take out. The Dodge had longer bolts. Can I run the Plymouth without a thermostat (thats how it came)or just get the correct size thermo?
Thanks.
