65 Barracuda Casting Numbers

Yeah a high compression 273. Great engine
Good for you.
Thanks! Definitely more excited just troubleshooting some lack of power now. Plugs were fouled (black carbon build up) so I’m assuming the carb is running to rich so I’m going to go factory and look at the idle speed and see if it’s where I need to be. Unless anyone else has another avenue of approach I should take. The guy that “rebuilt it” (owner before the last previous I got it from) didn’t bother taking out the spark plugs when he painted it. It had orange paint on the sides of the porcelain. Cleaned them up and gap checked them all good. Just gotta get some dielectric grease before I through the plugs on and adjust the carb
