Hello, I just joined and I'm in need of some assistance. I finally purchased the car I've wanted for years...73" dart swinger. The front clip and bumper are off a 72 though which I prefer. I was told that the motor is a 360, bored 30 over, internally balanced and professionally built by a guy name Bob Carter here in so Cal. The car sounds great also but I would like to know more about it and now I can't get a call back from the previous owner. What type oil should I use? Tranny fluid, octane fuel etc??? I don't even know the year of the motor. Any assistance would be greatly appreciated. Thanks, Gabe

 

Welcome From Another guy from So-CAL....

Gabe, I'll toss out a recommendation....
Engine Oil: 30w or 15W40
Transmission Fluid: ATF+4 Type
Octane: 87 >>>> Should run on 87. But if the engine pings / knocks... Move it up to 91 octane...

Just my 2 cent... Welcome again from Monrovia rite near Pasadena...

 

That's a wide open question!

We are going to need more information about the compression ratio etc. to give you credepal opinions.

Smile �� have a great day.
Bob will come over and fix you up!!!!!!

 

 

Gabe... Nice chatting with you today.... Anytime we can help.. Feel free to call of post it up here....

Cheers.

 

Unless it was a custom expensive rebuild It is externally balanced..The front dampener would be about 1" (318 style) wide for internal balance and 1 3/8" for stock external balance
