Slant six transplant ‘64 Barracuda
There's at least one more /6 pan...not shown
No this pan won't fit your car.
The rear sump pan shown is 70s/80s truck, I recently had an engine with a front sump out of a 64 pickup.
And OP I see you're listed as being from Savannah? RRR is by Macon. And member Marcus V is between Macon and Savannah, last I knew he had a 64/65ish valiant convertible..
I think that was a 273 car. Bit that was a few years ago, don't know if he still does.
He posts pretty rarely on here.
Mifht be some good parts/info sources for your car not too far from you....
I vaguely remember the lay of the land as I made that drive down interstate 16 a few years ago from I 75....
